Mischa Barton Bikini Pictures in Miami

Mischa Barton showed off her hot bikini body in a skimpy black two-piece lounging on the beach in Miami on Tuesday. The actress looked to be in good spirits as she chatted with a friend and worked on her tan. Mischa is currently focusing on her fashion career more so than acting, but whatever she's doing looks to be agreeing with her. She does have a couple movie projects in the works as well, so perhaps we'll be seeing more of Mischa in the coming year. For now though, joining the throngs of celebrities in bikinis, from Sofia Vergara to Katy Perry, seems like a great way to close out 2011.
