These competition shows are really pulling out all the stops for ratings! With American Idol snagging Mariah Carey and rumored to be bringing in Nicki Minaj and Diddy, among others, X-Factor has upped the ante as well. International star Justin Bieber has officially signed on to become a celebrity mentor to judge L.A. Reid on the upcoming season of the show. Details below.
TMZ has learned … Bieber agreed to be one of 4 celebrity mentors assigned to one of the 4 judges … Simon, L.A., Britney Spears and Demi Lovato.
Bieber agreed to help out L.A.’s squad … and yesterday, Justin went to a home in the Hollywood Hills to dish out some quality advice to the contestants.
It’s unclear which celebrities have been tapped to help out the other judges — but good luck doing better than Bieber.
