Having a blast in the tropical waters, Demi Lovato even re-enacted the iconic Dirty Dancing scene where Jennifer Grey leapt into Patrick Swayze’s arms. And yes, Wilmer Valderrama made the perfect catch.

The “Cool for the Summer” singer was beyond sexy in a black one-piece swimsuit with a deep–very deep–plunging V that reached her navel.
