Nick Jonas has been spotted on a date with a mystery girl in New York.

The Jonas Brothers singer - who has previously dated Selena Gomez and Delta Goodrem - was spotted at trendy eatery Beauty & Essex on Tuesday, where he fed his date lobster tacos.

"Nick came in to the restaurant with a really pretty brunette. They were clearly there on a romantic dinner date and ate lobster tacos and pot de crème, as they snuggled up in a booth. 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," a source told HollywoodLife.com.

Nick, 19, also managed to take things a little further with the mystery woman, with the witness adding, "They were so intimate. They shared a few pecks here and there."

Nick also played chaperone to Twilight star Ashley Greene - who previously dated his brother, Joe - at the weekend, as they attended the wedding of Jonas Brothers bass player Greg Garbo, who married musician Paris Carney.
