Nick Jonas New Girlfriend?

Nick Jonas Kisses Mystery Girl During Dinner Date In NYC

Sorry, ladies…we have bad news! Nick Jonas is already off the market and dating another girl — and we have details about their romantic date at the NYC hot spot, Beauty & Essex, April 18.

“Nick came in to the restaurant with a really pretty brunette,” an eyewitness tells . “They were clearly there on a romantic dinner date and ate lobster tacos and pot de crème, as they snuggled up in a booth.”

Adds the source, “At one point, Nick was feeding her a lobster taco and had his arm around her while they looked at the menu. He definitely took the lead and ordered for them both.”

It sounds like Nick’s romancing worked quite well, because the mystery brunette (who had long hair) was smitten.

“They were so intimate,” the eyewitness remembers. “They shared a few pecks here and there.”

What do you think of Nick’s newest secret relationship? Do YOU know who the mystery girl is?
