Did You Hear?

:: First Fall Out Boy goes on an indefinite break, now this —Pete Wentz and Ashlee Simpson-Wentz (not for much longer, anyway) are calling it quits after nearly three years of marriage, with Ashlee citing "irreconcilable differences" in the divorce papers. Well, at least the other Simpson sister will have a happy Valentine's Day with her new fiance. [MTV Buzzworthy]

:: Britney Spears is collaborating with will.i.am. Is there anyone left who hasn't collaborated with will.i.am? [EW Music Mix]

:: Cee Lo Green will have The Muppets as a backup band for his performance of "Fuck You" at the Grammys. So, this is acceptable, but Elmo hanging out with a pair of boobs is unconscionable?  [Spinner]

:: Glee creator Ryan Murphy is in talks to direct Willow Smith in an Annie remake. So don't be surprised if the Glee cast performs a mash-up of "Whip My Hair" and "Hard Knock Life". [Celebuzz]
