On tonight's The X Factor, 60 acts will get narrowed down to 24 during the "Judges' Homes" episode, which has each judge being assigned a category and pairing up with a music industry heavy-hitter. Britney teams up with will.i.am, Demi Lovato is with Nick Jonas, Simon Cowell is with Marc Anthony and L.A. Reid is with Justin Bieber.
