Simon Cowell has released an official preview of X Factor USA ahead of the show's debut on Wednesday, September 21 on American network, FOX. 

The trailer shows the four members of the panel, namely Cowell, Nicole Scherzinger, L.A Reid and Paula Abdul, facing nightmare judging scenarios.

The 'auditionees' are out of key and clueless, and prompt the judges to give the reactions that X Factor has become known for. 

Speaking of the promotional video, Cowell explained:

"I sort of 'dreamt' the promo - seriously I did. I woke up and I can't remember whether it was a nightmare or a dream but I remember laughing when I woke up and I quickly wrote it down."

"The idea was what was the most inappropriate thing I could wear and it was either going to be pink or yellow - so we got all these sweaters and the pink one just stood out!"
