There's no denying it now. Ashley Greene and Joe Jonas are "officially" a couple. RadarOnline.com has the photos of the hot twosome kissing on the streets of New York.

The Twilight star and the middle of the Jonas Brothers have been spotted together periodically since early July.  That's when Joe showed up in London for the Eclipse premiere and later took in a Kings of Leon concert with Ashley.

They were seen again in L.A. earlier this month and took it a step forward on Thursday when she cheered him on from the stands as Joe played baseball in NY.  Through it all, they have steadfastly refused to answer questions about their relationship.

But on Friday, after having lunch and shopping in NY's ShoHo district, they stopped and shared a discreet kiss on their way out of a store.

Maybe Joe's a little gun shy after all the talk surrounding his romances with Taylor Swift and most recently, Demi Lovato.

Says Demi, who appears with the Jonas Brothers in Disney's Camp Rock 2: The Final Tour, "It's not very much fun when you break up in a public relationship."
