Britney Spears, Demi Lovato New Judges on X Factor

Britney Spears and—as TMZ put it—"some other girl" appeared in New York today to present themselves as new judges on Simon Cowell's X Factor. That "other girl" has 15 Billboard Hot 100 hits, by the way, and her name is Demi Lovato. A photo of the two singing gals alongside Cowell and LA Reid appeared on Britney's Twitter page before the official announcement, reports Billboard, so Spears preempted the roll-out a second time (the first when her stunning $15 million contract broke online.)
