Sofia Vergara's Handsy Reunion

One month after Sofia Vergara said adios to deep-pocketed businessman beau Nick Loeb, they have found their way back to each other.

On Thursday night, the couple of two-plus years were snapped enjoying a cozy evening of dinner and clubbing in New York (left).

"They're definitely back on," a mole enthuses to Life & Style.

And making up for lost PDA time.

While chowing down at Bagatelle, they were "snuggling up together in the corner booth," a spy tells Us Weekly. "It seemed as if it was their first date all over again!"

Loeb even spoon-fed Vergara a sundae for dessert.

"Nick had his hand around Sofia and was rubbing her back and butt. She seemed really happy and energetic the whole evening," observes the L&S spy. "They couldn't get enough of each other. They left together hand in hand."

The "Modern Family" knockout, 39, reportedly called it quits with Loeb, 36, because of differing life philosophies.

"She is fiery and free-spirited and wants to enjoy life to the fullest by traveling and going to parties and events," an insider explained to People last month. "He's very concerned with his businesses, political aspirations and ultimately settling down."

But they're apparently determined to find common ground.

"There are compromises to work out on both sides," a Loeb confidant tells People, with another source explaining to Us, "They have a crazy relationship. They break up and make up. They fight hard and make up hard!"
