Marc Anthony

On the October 10 episode of The X Factor, we were introduced to a few new groups (LYLAS, Playback, Lyric 145), saw some fake houses where the judges supposedly live, and got to enjoy the judges’ reactions to their mentor assignments.

Simon Cowell's team!

Yep, the ex-husband of the woman who just left American Idol is reportedly joining The X-Factor.

TMZ's sources close to Marc Anthony say he recently signed a deal to be a celeb mentor for his buddy Simon's team on Season 2. If you remember, Simon "won" the first season with Melanie Amaro. Justin Bieber has already been named a guest mentor for L.A. Reid's team.

Do you...
