Worst Performance: Jason Brock
Coming across as a poor man's Adam Lambert, Jason Brock was way out of his league on The X Factor. We're still not sure why mentor L.A. Reid chose him over much better Over 25er David Correy – especially after an embarrassing "glitter explosion" set to Jennifer Lopez's "Dance Again." Indeed, it was a cringe-worthy first-time outing for the 35-year-old San Franciscan, who got slammed by Simon Cowell for being "utterly horrendous" during the disco-drenched, Vegas-caliber performance. The next week he was sent packing after an equally disastrous rendition of R. Kelly's "I Believe I Can Fly." Despite being the first to get the boot, "Mr. Entertainment" made the most of his time by pinching a stunned Mario Lopez's ass. He did it for the gays. And Japan.
