Justin Bieber has agreed to join the cast of X-Factor as the celebrity mentor for L.A. Reid team.  Each judge will have a celebrity mentor for this upcoming season and Justin Bieber will help out L.A. Reid. 

TMZ is reporting that Justin Bieber has already started giving advice to contestant in Beverly Hills.  I am not a X-Factor fan and honestly not a big television fan.  Even if I don't watch the show, I can tell that ratings should be good with Justin Bieber being on the show.

No other word has been giving about the three other guest mentors.  Does Justin Bieber make you want to watch X-Factor?
