The craziest sight during the 51st Annual Grammy Awards last night? An extremely pregnant M.I.A. performing "Paper Planes," then holding her own alongside Kanye West, Lil Wayne, T.I. and Jay-Z. I'm sure old-time Recording Academy members were like, "What the hell did I just watch?" Too bad M.I.A. didn't go into labor during the performance... Now that would've been a real show-stopper. Watch some fuzzy video of the performance here.
