Leonardo DiCaprio and Bar Refaeli Split?

Wooo hooo, happy days are here again! In Touch magazine is reporting that Leonardo DiCaprio is single again.

A source told In Touch Weekly that Bar Refaeli was seen partying in Las Vegas and "kept saying she needed to meet a hot guy." The insider added, "She was on the prowl."

DiCaprio and Rafaeli haven't been spotted together since July. And he's been making the rounds in the nightclub scene lately, which means one thing: he's on the prowl too! Mission: Leo is officially on.
