A very disgruntled Simon Cowell took to Twitter last night in the wake of a huge scheduling crisis for the US version of his hit show, The X Factor.

Fans had been eagerly anticipating last night's crucial episode where the judges finally reveal the 16 acts they are taking through to the live shows. Filmed at glamorous mansion homes across the USA, Simon and his fellow judges Demi Lovato, Britney Spears and LA Reid were joined by super star guests Marc Anthony, Nick Jonas, Will-i-am and Justin Bieber to help choose their contestants.

Trouble started when a major league baseball game was delayed due to rain. After 40 minutes the show DID start to air, then inexplicably, FOX chose to air a rerun of The Mindy Project. In a FURTHER flurry of confusion, a technical error saw the East Coast feed air simultaneously on the West Coast. X Factor fans were thrown by the messy, erratic scheduling and took to Twitter to air their anger and disappointment.

Even the official X Factor USA twitter seemed oblivious to FOX's tinkering with the schedule and it appeared the West Coast WAS about to see the full "Judges Homes" episode but that was later cut too. But to add to the drama, CTV in Canada continued to air the majority of the episode that had been cut in the USA so all but two of the Final 16 have been leaked. Disappointed fans are now trying to avoid stumbling across the leaks on Twitter, Facebook, blogs and forums.

In more bad news for the show, FOX have rescheduled the cut episode on Tuesday which will also put it head to head with its rival NBC's The Voice. This could spell disaster as The Voice has been winning the ratings battle in recent weeks. Coupled with the leaked finalists, ratings could suffer greatly when FOX do finally air the show next week.

Sources close to Simon report he is "furious" with FOX for tampering so badly with The X Factor USA scheduling. The series was already due an unwelcome 2 week hiatus for the Major League Baseball games that FOX are due to air. And even the Live Show schedule could be postponed if FOX get the rights to broadcast Game #7 of the series.

Simon tweeted his anger last night and confirmed that The X Factor would be shown next Tuesday at 8pm ET.

So to confirm, the rescheduled Judges Homes Final Reveal episode will now air Tuesday, 23rd October at 8pm ET/ 7pm C.

We wont be posting spoilers until after the show airs next week.
