Demi Lovato & Wilmer Valderrama Make Out and Channel Dirty Dancing in St. Barts

The two have been dating on and off since 2010

Whew, is it getting hot in here?!

Demi Lovato and boyfriend Wilmer Valderrama were photographed on Wednesday in the middle of a super steamy make-out session in the ocean during a trip to St. Barts. The 35-year-old actor was also seen lifting the 23-year-old singer up, Dirty Dancing-style.

During their visit to the gorgeous Caribbean island, the two were also joined by Victoria's Secret models as well as by Lovato's longtime friends and Camp Rock co-stars Nick Jonas, 23, who is forming a new record label with her, and Joe Jonas, 26, Lovato's ex-boyfriend.

She posted several photos of the group on Instagram with the hashtag #somethingbigiscoming16. Nick had recently posted on his own Instagram page a pic of himself serenading several of the models and had used the same hashtag.
