Who knew they were friends?!

Leonardo DiCaprio is living the high life on his mega yacht in St. Barth, and he allowed Robin Thicke to come and join in on the fun! The singer made the most of his stay on the actor's charter by hopping on a jet ski and whizzing around in the water. Fun!

We haven't seen The Revenant star with his girlfriend Kelly Rohrbach lately... we smell a breakup! When we first heard the rumors the A-list hunk stole Scott Disick's newest conquest we were skeptical, but maybe there's some truth to those reports?

The Oscar nominee is certainly enjoying his bro vacay in the islands!
