Katy Perry: Bikini in the Bahamas!

Katy Perry slips into a cute bikini and hits the water slides at Atlantis Paradise Island in Nassau, Bahamas on Sunday (July 18).

Last night, the 25-year-old California Gurl performed a sold-out concert inside the Grand Ballroom in Atlantis.

Katy tweeted, “BERMUDA, BAHAMAS, CUMMON BABY MAMA!” Har har.

Ms. Perry‘s entourage in the Bahamas included her assistant Suzanne Sansone and her gays — stylist Logan Horne, jewelry designer Markus Molinari, singer Ferras, hairstylist Aaron Light, and her brother (and actor) David Hudson.
