Mischa Barton’s ‘California Gurls’ Bikini: Yay or Nay? (PHOTOS)

Mischa Barton looked like one of Katy Perry’s “California Gurls” (you know: “Daisy Dukes, bikinis on top”) when she was spotted hanging out on a boat in St. Tropez earlier this week.

The O.C. star wore some short jean shorts and a floral bikini top as she chatted with friends. When the blonde beauty stood up to light a smoke, she exposed a green patch on her bottom.
