Kristin Davis stripped down to her bikini top and colorful shorts to hit the beach yesterday afternoon in St. Barts. While her Sex and the City costar Sarah Jessica Parker was trying to stay warm at her premiere in London, Kristin was basking in a very different climate. Keeping Kristin company on her latest vacation is her boyfriend, the photographer Russell James. The duo has been dating for the better part of the year, and it looks like they decided to spend some of 2009's last days in a romantic way.
