Exclusive: Demi Pranks Simon on 'X Factor'


Only one judge returns alongside Simon Cowell for this season of The X Factor, and after her extensive back-and-forth banter with him last year, Demi Lovato is eager to play some pranks on the cantankerous Cowell.

In ET's exclusive sneak peek at the X Factor's Season 3 premiere, Demi Lovato, the only returning judge from Season 2 other than Cowell, seizes the opportunity to prank him when she spots him dozing off on a chair.

PICS: Stars Without Makeup!

As you might imagine, the tetchy judge isn't too thrilled when Lovato startles him from his sleep with a forceful shake and a false alarm that there's fire in the building.

Simon's streak of dissatisfaction continues when the auditions kick off with a poor rendition of Ike & Tina Turner's "River Deep—Mountain High," which leaves him and the rest of the panel with an unpleasant ringing in their ears.

However, Cowell finally gets some proper affection to compensate for the day's misdeeds when the contestant smothers him with kisses all over his cheeks and neck before leaving the stage.
