Hungarian shadow theatre act Attraction won the 2013 series of Britain's Got Talent last night in what turned out to be a dramatic finale.

Viola player Natalie Holt pelted Simon Cowell with eggs during the live final show and has since apologised, admitting her actions were 'silly'.

The musician, who jumped to the front of the stage as brothers Richard and Adam were performing, appeared on the talent show in 2012, along with her band Raven Quartet.

Bemused opera act Richard and Adam Johnson carried on singing as she stood between them launching the eggs one by one.

Richard said: “I thought Simon was going to get killed. She had what looked like a hard, shiny object.”

Natalie - a BAFTA-nominated composer who appeared in the closing ceremony of last summer's Olympics - was performing as a backing musician for the duo, and has subsequently apologised for her actions.

In a statement released by the show she said: 'I want to apologise to Richard and Adam for overshadowing their performance. I’ve never done anything like this before and in hindsight I have realised it was a silly thing to do.'

A spokesman added 'During tonight’s show an incident took place during the finale of Richard and Adam’s performance.

'Natalie Holt (age 30) was part of the backing group for their performance and as a result of her misguided actions the police were called. However, we have decided to take no further action at this stage.'

Judge Amanda Holden spoke of her anger at the disruption Natalie's appearance on stage caused and she branded her 'a stupid cow' for the apparent act of protest.

Simon had to remove his jacket and was left with yolk on his shirt following the attack, but he didn't seem too fazed.

Although the egging occurred in the middle of their performance, Richard and Adam were not put off and they were later praised for their professional attitude.

Simon said he thought the woman was throwing sandwiches and assumed it was part of the performance. He said: 'I thought it was part of the act, I thought they were throwing sandwiches.'

Removing his egg-smeared jacket, he told the audience and 13million viewers: “I sent a tweet yesterday saying I don’t like eggs. I really don’t like them now. I’ve no idea what that was all about, so whoever’s watching, I apologise.”

Simon declined to press charges. At the end of the show he quipped: “I would say that Britain’s Got Talent has got the Eggs-Factor.”

Disabled comedian Jack Carroll was the next act to perform on stage and he used the opportunity to make a joke about the situation. He began: 'Can I just say, I was going to run on and throw some eggs, so thanks for ruining that.'

Simon obviously didn't let the drama ruin his night as he was spotted laughing with Sinitta at the after show wrap party at 45 Park Lane - minus his egg stained jacket!

Voting results from last nights final reveal that Attraction got 27% of the vote, Jack Carroll 20%, Richard & Adam 15.4% with Steve Hewlett in 4th place.

With over 13 million viewers the show was an amazing success and Simon confirmed that all four judges will be returning for the 2014 series.

Simon Cowell has said he is not worried if Attraction win Britain's Got Talent - despite being from Hungary saying: "I think it's testament to how we are as a country.

"We want everyone to do well, no matter where they're from. It's a positive, not a negative."

He picked out Attraction and Jack Carroll as the likely winners, but said there is a chance of a shock after watching rehearsals - especially with one of the losing semi-finalists getting a judges' wildcard spot.

On complaints about professional acts being passed off as amateurs, Simon added: "Whether you're professional or amateur, you enter this competition because you need a break.

Also remember, it's not me, it's the public that vote."

He also hinted that David Walliams, Amanda Holden and Alesha Dixon will return. He said: "We're going to make an announcement on tonight's show."

He then jokingly mocked Alesha by saying she has "11 boyfriends" and her type is "anything with two legs".

And on David he said: "It's like having a new dog which hasn't been trained properly. You always get the feeling they are going to bite you."

How do you think the series has gone so far?

This is my favorite series so far. Its been a lot of fun. The talent has been really good and we have lots of variety. I honestly can’t call a winner, which makes it exciting!

Are you happy with the ratings?

I’m definitely happy with ratings. They have been really good. Better than I could have hoped.

Do you prefer doing the show live or do you still get nervous doing live TV?

Only when David is around! It’s like having a new dog, which hasn’t been trained properly and you always get the feeling they are going to bite you at any time.

Can David embarrass you or do you lay down some rules?

The more I lay down ground rules, the more David breaks them. It’s completely pointless. The more I tell him to behave the more worse he is. I just shut my eyes and hope for the best.

The live final is tonight - who are you most looking forward to seeing?

I’m really excited about tonight. All of the contestants are all up for it this year. They all want to win and I think it could be one of them finals where someone unexpected can pull it out of the bag and win it.

Have you got a favourite?

I have lots of favorites!

How do you respond to people who say it’s wrong for children to be on the show – that the pressure’s too much?

I don’t like kids that are pushed into things by stage mums, but when I can see they are having a good time, they’re excited and enjoying the process, then I think its wrong to discriminate. I would say to anyone that is worried about the kids to come down to the show and see how much they are enjoying it.

Knowing now that Alice Fredenham became particularly upset following her semi-final, are you disappointed she didn’t deliver as good a performance as in the audition?

Yes, but that’s the reason we do live shows to see how people can deal with the pressure as that’s what it will be like in the real world, in this industry.

I think its testament to how we are as a country. We want everyone to do well, no matter where they are from. It’s a positive not a negative.

There has also been criticism of ‘professional’ acts like the Johnson Brothers and Francine Lewis appearing in the show, how do you respond to that criticism?

I don’t like rules. I think if you take the rules away, which we pretty much have, then the competition is open to anyone. Whether you are professional or amateur, you enter this competition because you need a break. Also remember, It’s not me, it’s the public that vote!

There has been some jokes about Alesha using the show to get a boyfriend. Are you surprised she is single or not married up by now?

I’ve heard rumor that she has 11 boyfriends, and I actually believe it!

What kind of man do you think she would go for or would suit her?

Anyone with two legs!

This year you have easily beaten The Voice in the ratings, does this make you happy?

I’ve kind of got over this crazy competitive thing I used to have with other shows. I think if you win then you deserve to win and if you lose you deserve to lose. You can’t take anything for granted.

Are you surprised they are moving their first live show to a Friday to avoid a clash with the BGT final?

I think it’s the most sensible piece of scheduling I have seen in years. I actually compliment the BBC for thinking of the viewers first other than a silly ratings race.

Have you enjoyed this series more than last year?

I have enjoyed the series more this year. We’ve all had a lot fun and all get on really well as a panel. From the minute we started filming, we’ve had a good time.

What has been the best and worst moment on BGT so far?

The best moment is probably when you feel that you have genuinely discovered a star for the first time.

The worst time is doing the questions with David on Britain’s Got More Talent.

Will you do the show again next year? Are you happy with the judging panel?

I’m almost certain ill be back. We are going to make an announcement on tonight’s show about next year’s panel.

You’re now jetting to the US for US X Factor – what are the biggest differences for you as a judge between doing BGT in the spring and US XF in the autumn?

We don’t have dogs on X Factor USA.

Have you got used to splitting your time – with half the year in the UK, and half in the US?

Yes, I like splitting the time. I like going back to LA and look forward coming home.

The Britain's Got Talent Final is tonight 7.30pm ITV1.

In an exclusive interview with The Sun today, Demi Lovato talks Simon Cowell, X Factor and her new album.

Are there any surprises on the new album?

I think my fans know everything about me! But there are some songs that are more personal than I’ve ever been.

Warrior is a song that’s super-personal but I’m not going to elaborate on that. I feel like if you want to know what it’s about you can listen to the song! But I definitely do get more open and vulnerable.

What was it like working with Simon Cowell?

Working with him is really great. He’s a really, really cool guy, not what people expect, I think. He’s not as mean as he comes across.

Are you close?

Definitely. I’ve been able to tell him things that I don’t tell the public — about my personal experiences, my journey and what I’ve been through. He’s been really, really cool about everything. Way deep down there, he’s a good guy.

But on the surface...Well, it’s Simon Cowell! What do you think?

Does he tease you guys?

He teases us for sure. Just watch the show. You’ll see, he’s constantly teasing me.

Is Simon as vain as people make him out to be?

Definitely! He wears his sunglasses indoors. It’s funny. It’s a part of who he is.

Is he big into grooming?

Yeah, he’s always blowdrying his hair.

What was Britney Spears like to work with?

She was really great and super down-to-Earth. I’m going to miss her this season.

You have a bit in common, both being child stars who have run into difficulties. Did you ever have a heart-to-heart?

We’ve definitely bonded, I think because we’ve been through the same stuff. But if we did have a heart-to-heart I probably wouldn’t tell a magazine about it! It’s pretty obvious that we’ve been through some of the same things for sure.

Do you keep in touch?

We have kept in touch. Our moms have become super-close, which is really random. It’s super-funny.

What made you decide to be so open with problems in private life in the past?

I went through bullying and it was a very difficult time for me. It ended up changing my life and I went through a lot of things because of that.

When you’re bullied by someone, it doesn’t mean that you have to be thrown in a trashcan by the big bully at school or that somebody physically hurt you or something. There’s verbal harassment, which is sometimes even worse.

Who is your favourite British person?

I really like Adele.

What is your new single, Heart Attack, about?

Heart Attack is the feeling you get when you’re about to fall in love.

Heart attack is like, “Oh no, I’m about to fall in love and I’m not used to that. I’m used to manipulating and abusing guys and being a game-player — and now being I’m feeling something serious coming on and I don’t know how to handle it”.

Is that from personal experience?

I don’t sing about stuff that’s not from personal experience any more.

After a full on week of Britain's Got Talent live finals, Simon Cowell has revealed in two new interviews why he finds marriage "boring", how he thinks he now has got The X Factor USA "just right" and why he will NEVER retire.

The Telegraph's Celia Walden spoke to Simon at Fountain Studios in Wembley where the BGT finals are filmed. You can read the FULL interview HERE

“Last year, doing BGT felt like sitting in a room with a blindfold on,” he laments, sipping a cup of Chinese herbal tea. “I didn’t have a clue whether people were fed up with what we were doing. This season the mixture is so weird that it works: we’ve got everything from dancing nuns to opera singers. Plus it does feel like normal people with a talent rather than semi-professional people, which is great.”

He’s willing to admit that Adam and Richard, the Welsh opera-singing, sandwich-making duo, “are probably the most talented and definitely the most popular”. And — waving aside comments by Sir Bruce Forsyth on the “emotional damage” younger acts might suffer from the pressure — he believes that 11-year-old Arisxandra Libantino has a chance.

“There was something very charming about Pudsey the dog last year, and it definitely helps if you have a story. Then again, I would have put my house on Susan Boyle winning, so you never really know what’s going to happen. I like that.”

he favours nights in over red-carpet dos; in conversation, he’s more of a listener than a dominator.

“I can’t bear small talk,” he explains. “You’ll never see me in the 7.30 for 8pm segment of an evening because that means having to make conversation and I do get shy about that.” He accepts that “people clapping or being excited to see you is not a bad feeling — it’s impossible not to like that — but I don’t get off on it”.

One wonders whether, now that he’s single again (he called off his engagement to make-up artist Mezhgan Hussainy last year), Cowell gets lonely in his Citizen Kane-like Beverly Hills mansion.

“Actually, being on my own is the best thing in the world. It’s like breathing in oxygen — I can really switch off then.” He keeps vampiric hours, going to bed at 2am or 3am, rising late and “working out for an hour or so to a movie”.

Has anyone ever broken his heart? “No.” Has he ever been in love? “I have a different kind of love,” he sighs. “The love I have for my ex-girlfriends will always be there, so I think that’s true love. People confuse ego, lust, insecurity with true love. But for me, whether it’s Jackie, Mezhgan, Sinitta or Terri, they will be in my life for ever. I genuinely love them.”

How does he know that women genuinely love him — that the stardom, the handbags and the parting-gift LA mansions aren’t part of the appeal? “I know. I don’t have the Mick Hucknall effect. I’m aware that I can get girls because I’m on TV, and I don’t believe I’m God’s gift to women, but I think you know when it’s genuine.”

He says, he’s learnt how to manage stress. “I think of stress as the creator of cancer and heart attacks, like a tiny little ball you feed. I believe that one of the reasons I’ve never got ill is that I’m not stressed. I’ve seen things in other parts of the world that put everything in perspective.” He concedes, however, that had he become famous as a young man, “I would not be alive today”.

He’s not so sanguine about retirement. “I’d rather drop dead doing my job. The idea of getting up in the morning to play golf makes me want to jump off a bridge.”

In a recent phone interview from his native London, Simon recalled enjoying talent shows like Opportunity Knocks and New Faces as a child.

And he described how a few years ago, amid the boom of singing competitions, he hatched the idea for the broader-based talent show America's Got Talent emerged as. He was watching a singing show in Britain when a contestant warbled a too-familiar song, and very badly, "and I remember thinking: 'I'd actually rather watch a dancing dog than listen to her.'

"Then I said to myself, 'I used to love that kind of show! Why don't we bring back that type of show again?"'

So he did. America's Got Talent (the first in Cowell's global Got Talent franchise, with original versions of the format now produced in 56 territories) premiered in 2006. And last year (fittingly) a dog act, Olate Dogs, won the $1 million prize.

"The new panel has jelled very well. There's really good chemistry with the judges and the host (Nick Cannon)," he said. He also sang the praises of the series' new producer, Sam Donnelly. "She's totally revitalized the American show. It's by far the best we've done."

Talking about the third season of The X Factor USA, Simon reveals he is optimistic about the show's future after a major shake up of the judging panel. Britney Spears and LA Reid have been replaced by Kelly Rowland and Paulina Rubio - is it a formula he thinks will work?

"If you'd asked me that question even a month ago," Cowell replied, "I would have said I honestly don't know." But recent auditions in Charleston, S.C., were "by far the best two days we've shot" since the series began, he declared.

"It suddenly just clicked. And there's one audition in particular that's probably one of my favorites that I've ever been involved in -- a one-in-10-million audition. I can't stop thinking about it.

"I think we may have got it right," he summed up.

The X Factor USA continues auditions in Long Island New York on June 11th and the third season will air on FOX in the fall. Exact air dates TBC.
