Hookup Alert: Chace Crawford and Bar Refaeli

Time will tell if Chace Crawford can develop into an actor of Leonardo DiCaprio’s caliber. But apparently he’s already giving Leo a run for his money in the ladies’ man department.

Just Jared reports that the Gossip Girl heartthrob was spotted getting hot and heavy with DiCaprio’s sometimes-girlfriend, Bar Refaeli, on the dance floor on Friday night at New York’s 1Oak, and there was even a bit of buttock-fondling involved.

According to a source, Crawford and Refaeli were “dancing on each other, swaying their hips together from side to side” to the strains of Jay-Z’s “Run This Town.”

“At one point, Bar reached down and grabbed Chace’s backside. They were very affectionate with each other,” the mole added.

Says another source, “Bar and Chace have been spending a lot of time together since Bar is in town and attending NY Fashion Week events.”

Sounds like Bar really has her hands full with her new man!
