Brittany's coming back for more X Factor.

Britney Spears may be back for a second season of "X Factor."  At a red carpet event, the pop star told "Broadway World" that she is "definitely" planning on returning to "X Factor" as a judge next year.  Britney answered a series of questions about the show, saying that "it's a lot of fun" and that she's enjoying getting to "sit back and be entertained."  The Fox show reportedly forked over 18-million-dollars to have Spears on as a judge on its second season.  The network has not announced next season's judges yet, so Britney's spot for next year hasn't been officially confirmed.  "X Factor" is in its second week of live shows, with new hosts Khloe Kardashian and Mario Lopez.  Thursday's episode will be the first live eliminations.
