LeAnn Rimes wore a bikini yesterday for a celebration in Malibu. She met up with her girlfriends to watch the sunset on the beach after a recent surgery. LeAnn's apparently been dealing with some discomfort that she described as "jaw pain [that] makes your whole head pound." Yesterday, though, she was in top form to lounge with her pals. She tweeted, "The pain is subsiding finally for a moment. My head has been vibrating all day. Maybe the sand under my feet is helping." LeAnn's looking forward more fun today when she and her husband Eddie Cibrian check out the Giants vs. Patriots action during the Super Bowl.
