Mischa Barton, Kimora Lee Simmons and supermodels Elle Macpherson and Stephanie Seymour aren’t the only stars stripping down for a tropical holiday!

Over the weekend, Katy Perry was snapped on the beach when the pop star escaped to Kauai for the Christmas break.

Her husband, Russell Brand, was nowhere to be seen—People says he came along on the trip, other reports claim he was spotted in England over the holidays—but the “Teenage Dream” singer looked relaxed as she hit the water in a skimpy (though not exactly supportive) two-piece swimsuit that revealed her slammin’ figure.

The pop star, who rented a private luxury villa, was spotted with friends during her romp in the surf.
