Leonardo DiCaprio ran an experiment on New Year's Day -- can a guy with the beard of a homeless dude get a bunch of chicks to party with him in St. Barts?
You can see the results of Dr. DiCaprio's testing in these photos. Go ahead and click through the gallery -- he gathered a lot of evidence. Very hot evidence.
Leo shuttled a bunch of chicks -- half a dozen or so -- to a private beach only accessible by boat to celebrate 2015. While he smoked a vape pen and took in the scenery ... a staff of 5 served Leo and co. from a full bar on the beach.
