What's a newly single star to do in New York City? Step out on the town with her girlfriends, of course!
Sofia Vergara, who recently split with longtime beau Nick Loeb, did just that alongside Jessica Alba and sisters Samantha Ronson and Charlotte Ronson on Thursday.
The celebrity clique partied the night away at the Dream Downtown Hotel's PH-D Rooftop Lounge, arriving around 1 a.m.
The ladies "were all enjoying themselves and taking lots pictures of each other," says an onlooker. "Sofia was relaxed and was all about having fun."
