Beyoncé Knowles looked beautiful when she walked down the red carpet at the Grammy Awards in LA today. She wore a fitted black and white jumpsuit from OSMAN by Osman Yousefzada. Beyoncé has been the subject of a lot of speculation as of late, with many fans suspecting that she'll do a surprise performance during the show. When asked about singing at the Grammys a few weeks ago, Beyoncé remained coy, saying that she "doesn't know about that." Whether she performs or not, Beyoncé will take the stage during the show since she is slated to present an award and is up for the best traditional R&B performance award for "Love on Top."
