Rihanna bought herself a snack while shopping at the Grove Wednesday evening, but she got an even sweeter treat at her birthday party later that night. The singer celebrated her 20th birthday at Les Deux with Kanye, Wilmer and her maybe-boyfriend Chris Brown. The party included a cupcake fight and a special a capella version of "Happy Birthday" sung by Chris. Rihanna and Chris were looking mighty cozy at some post-Grammy events but have been denying being a couple but it looks like it's going to be hard to keep this cute love story under wraps for much longer.
