Cameron Diaz Bikini Pictures in Hawaii

Cameron Diaz wore a bikini yesterday for an afternoon at the beach in Hawaii. She was surrounded by friends for the outing, which reportedly included a stint swimming with dolphins! In addition to showing off her amazing physique in the L*SPACE two piece, Cameron also debuted a platinum blond hair color and new cut.

She's starting 2012 with a new look, and possibly a fresh start in her love life. Despite a rumored romance with Diddy following her end-of-year split from Alex Rodriguez, Cameron rang in Jan. 1 without the rapper. Diddy was one of the many celebrities partying on New Year's Eve, and he hosted a bash in Miami that brought out friends like Rihanna and Gayle King. Alex Rodriguez had his own star-studded party in Cabo, where he mingled with pal George Clooney. George and Alex have even more to talk about now that they're both dating former WWE stars; George is going strong with Stacy Keibler, while Alex is dating Torrie Wilson.
