Kate Walsh Bikini Pictures

Kate Walsh showed off her bikini body when she hit the beach in Miami yesterday. Kate, who turned 45 back in October, wore a black two-piece as she lounged with a small group of friends on beachside chaises before taking a dip in the ocean. Kate is currently enjoying her time off after wrapping filming for the final season of Private Practice. The final episode for Private Practice is expected to air sometime in early 2013, but there has been some fan buzz that Kate's Addison could make a return to her original haunt, Grey's Anatomy. Kate's now had time to hit the party scene. She was most recently spotted celebrating at last week's Rodeo Walk of Style event with Drew Barrymore and Cat Deeley in LA.
