Merry Christmas!! She spent seven straight years playing Dr. Addison Montgomery on Private Practice and Grey’s Anatomy and Kate Walsh continued to flaunt her incredible bikini body, and celebrate the end of the ABC spin-off in Miami Beach Thursday. The Private Practice pair, who were also spotted strolling on the sand Wednesday, emerged from the Atlantic Ocean drenched after a swim. ‘Happy Thurrrrrrzzzzdayin’ tw’eeps!’ the gorgeous redhead tweeted to her 345,000 followers. According to Celebuzz, the flame-haired beauty relies on celebrity trainer Juliet Kaska’s Pilates classes to keep her toned. That’s nice to know! She’s really hot and just the right age that I’m looking for. Too bad she has a partner but that really doesn’t mean anything in Hollywood. Going to keep my options open.
