Demi Lovato and Wilmer Valderrama are presently on vacation in St. Barts, and it seems like their romance is heating up.

In a black cut-out one-piece, the 23-year-old “Cool for the Summer” singer looked stunning. She and Wilmer looked to be having a good time in the sparkling blue waves.

The That 70s Show alum raised the pop princess in the air at one point, much like in the legendary Dirty Dancing sequence!

Demi was overjoyed as her attractive lover lifted her up and opened her arms wide.

Before heading into the ocean, the couple took in the scenery, hugging and kissing on the beach – not holding back.

Before they stripped down to their swimming shorts, Demi donned a lovely white lace romper and Wilmer wore a black tank top.

Wilmer and Demi went on a date later that evening, when Nick Jonas joined them for dinner. She shared a sweet photo of the three having fun on the Caribbean island.

“😍😍😍😍😍 I love these pics so much… Sorry @nickjonas for third wheeling you but your bromance third wheels me too!!!” she posted.

The pair has been together for nearly five years, so their newest vacation is really just a sample of all their adorable photos from the past.

We’re sure the sun, beach, and sea fire up their sex urges, and these lifelong lovebirds aren’t afraid to display their affection for everyone to see!
