Simon Cowell a Gentle-Turned-Nasty Judge in 'X Factor' Promo

After teasing a kindler, gentler version of himself, Simon Cowell lets his inner nastiness shine in a new extended promo for Fox's highly anticipated singing competition, "The X Factor," which premiered on July 12.

The clip opens with Cowell and the rest of the judges - Paula Abdul, Nicole Scherzinger and Antonio "L.A." Reid - judging a young girl singing the "Annie" classic "The Sun Will Come Out Tomorrow" a little too leniently, with a pink sweater-clad Cowell exclaiming, "I love your spirit!" A voiceover from Cowell continues the loveliest, proclaiming, "I want to make people's dreams come true. I even think about the environment!"

And then Cowell wakes up in bed, rubs his face and says, "Wow, what a horrible nightmare!" Soon, the viewer is watching clips of Cowell calling contestants "absolute rubbish" and "deluded".

"The X Factor" premieres September 21 on Fox.
