Sienna Miller Bikinis in Barbados (PHOTOS)

What’s a girl to do after a tireless year of home-wrecking marriages and rekindling romance with her own cheating ex? Beach trip!

Carnally-industrious Sienna Miller and girlfriends skipped, and splashed along the sandy shores of Barbados over the New Year’s Eve holiday. Jude Law made a pit stop in Sienna’s equatorial retreat prior to the turn of the year, but he was long gone by the time the serious 2010 beach frolicking began.
