Just days after Kate Hudson and Nick Jonas both tried to dance around questions about their possible romance, the two were spotted out together.

While Demi Lovato performed her new single "Confident" at gay bar Industry in New York City, the 36-year-old actress and 23-year-old singer hung out backstage. "They were dancing very close," a witness told Us Weekly. "It looked like a romantic date for the two of them." The rumored couple then headed to Up&Down, but left separately.

Apparently, this wasn't their first time seeing each other during Hudson's trip to NYC. "She saw Nick a few times," a source close to her also told Us Weekly. "And they had fun."

Rumors of romance first sparked in September when Hudson was seen at a few of Jonas' concerts. They were then photographed together at Disney World, as HNGN previously reported.

While on "The Ellen DeGeneres Show" earlier this week, Jonas told the host he was "alone," implying he is single, even though DeGeneres made sure to point out that it doesn't seem like he's been alone lately. Hudson doesn't seem to want to admit to anything either because, Wednesday, she appeared on Bravo's "Watch What Happens Live" and completely avoided answering a fan's question about the romance. "I don't like addressing any kind of gossip," was all Hudson would say when host Andy Cohen told her he hopes something is going on.
