Chace Crawford Is Hot In Hollywood

Chace Crawford is stepping up his game to become Hollywood's hottest hunk - he's reportedly dating Tinseltown's main poster-boy Leonardo DiCaprio's supermodel ex.

The Titanic heartthrob ended his relationship with beauty Bar Refaeli earlier this summer.

And it looks as though Crawford is keen to step into the actor's shoes - he was spotted dancing with the stunner in New York on Friday, according to JustJared.com.

A source tells the site, "(They were) dancing on each other, swaying their hips together from side to side.

"At one point, Bar reached down and grabbed Chace's backside. They were very affectionate with each other. Bar and Chace have been spending a lot of time together since Bar is in town and attending Ny Fashion Week events."

The Gossip Girl actor has been linked to a string of Hollywood beauties recently, including Twilight star Ashley Greene last month.
