Sorry Niall! Demi Lovato Left 'Sweating' After Steamy Performance On X Factor USA

While we're all wondering when Demi Lovato and One Direction star Niall Horan will get it on, the Irish singer might be a little sad when he finds out that the teen was a little taken by a steamy performance at the recent X Factor USA auditions.

On Wednesday (June 27), Troy Kurtis, an ex Latin boy band Menudo took to the stage performing a sexy Spanish song. L.A. Reid apparently joked that Demi had been a little 'turned on' by the performance, as according to Ace Showbiz, he said: (Demi's) sweating, she's giggling!.

While Britney allegedly chimed in that it had been very sexy. Demi kept it cute in Providence earlier this week, as she wore a long-sleeve floral print frock with a black vest, while Britney was a knock-out in her tight-fighting red dress.

Word has it that Britney is actually shaping up to be the toughest judge on the panel. Watch out Simon!

"She knows it takes more than having a good singing voice and that you have to beentertainingand have that 'wow' factor. She can really tell the difference between a good singer and a great performer," a source said.

Fans go crazy for Britney Spears at the auditions...
