Kate Bosworth's Beach Bikini

Kate Bosworth enjoys a fun-filled afternoon with two gal pals — including high school best friend Ary — on Friday afternoon Maui, Hawaii.

The bikini-bodied girlfriends play-wrestled on the beach and fooled around in the water, capturing moments together on a digital camera.

Looks like it was a girls-only vacation as British male model boyfriend James Rousseau did not join in on the fun.
