Leo DiCaprio -- The Topless Babe Yacht Party

Leonardo DiCaprio is clearly enjoying his single status and partied it up on a yacht with a bunch of hot bikini babes in Australia over the holiday weekend.

Along with all the sexy chicks -- some of whom were topless -- the 38-year-old "Django Unchained" star also hung out with his wingmen Jonah Hill and Lukas Haas.

Up until around two months ago, DiCaprio was dating Victoria's Secret supermodel Erin Heatherton.
