Chace Crawford and Bar Refaeli are getting close!

A new love story is making its base. The Gossip Girl hunk and Sports Illustrated cover model are getting over friendly with each other. Chace Crawford and Bar Refaeli are 24 and shared some special moments on Friday night (September 11) at NYC hotspot 1Oak. A partygoer exclusively tells JustJared.com, During Jay-Z's "Run This Town," 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." Another source reveals, "Bar and Chace have been spending a lot of time together since Bar is town and attending NY Fashion Week events."

Hollywood is all about changing partners. Last month Chace was seen kissing Ashley Greene and Bar has been linked to Brazilian polo player and entrepreneur Ricardo Mansur. Enjoy the pictures of Bar Refaeli.
