Demi Lovato and Wilmer Valderrama are so in love, they clearly don't care who sees their intense makeout sessions!
The singer and her 35-year-old boyfriend got down and dirty while on vacation in St. Bart's this week, locking lips during a dip in the ocean.
The 23-year-old even reenacted the famous lift from Dirty Dancing with the help of her actor beau.
"I wish I could put into words how grateful I am for this man," Demi once wrote on Instagram of the That '70s Show alum. "But my love has grown to a level that words could never possibly express how much this man completes me."
