The pair, who had been dating since January 2010, split in early May.
On June 7 in NYC, “They attended a private party at WIP before heading over to Soho House at 9 p.m.,” an eyewitness tells Life & Style. “Nick and Sofia hung out with friends on the rooftop and were clearly enjoying each other’s company. They’re definitely back on.”
Adds the eyewitness, “Nick had his hand around Sofia and was rubbing her back and butt,” the eyewitness says. “She seemed really happy and energetic the whole evening. They couldn’t get enough of each other. They left together hand in hand.”
This was the second sighting of the couple: They were spotted at Max Brenner’s Chocolate Shop in NYC over the weekend.
