Katy Perry showed off her super curvaceous bikini body on the beach in Hawaii.
The California Gurl wore a tiny two-piece with a plunging halter top, leaving next to nothing to the imagination.
Katy has just wrapped up her world tour and is taking a break before two concert appearances in Asia in mid-January.
Hubby Russell Brand is with her on the island of Kauai. They're staying with friends in a private villa rented for the holidays...where he is no doubt enjoying the view of his wife.
