Nick Jonas and actress Kate Hudson were spotted at Demi Lovato's party on Thursday amidst dating rumors.

The couple was seen at the Industry Club in New York City for Lovato's new single "Confidence" but did not show up together.

"I'm 23, single and loving life," Jonas told Entertainment Tonight. "And in any moment, I'm just trying to have as much fun as possible... I do live a public life and, for whatever reason, people are interested in that."

An eye witness said the "Jealous" singer snuck into Hudson's hotel room after the party. Are they just hooking up?

The "Almost Famous" actress runs in the same circle as Jonas, and they are both on the rebound. Hudson called off her engagement with Matthew Bellamy while Jonas broke up with former beauty queen Olivia Culpo.

Jonas and Hudson continue to end up in the same places. Is it just a coincidence? Last month, they were spotted together at Disney World and then later in Miami.

Meanwhile, a source close to Hudson told People on Oct. 8 that she and Jonas was "just a fling."

"It's definitely not anything serious," the source said. "They are both single and seeing other people too. Kate's mostly focusing on her boys and doesn't want a serious relationship right now."

Jonas admitted to "dating and hanging out" with people during the LA premiere of DirecTV's "Kingdom" Season 2 on Tuesday.

"I am single, but I'm hanging out with people and just getting to know people and enjoying seeing what's out there," he said.

He's out there, single and ready to mingle, ladies! Will Hudson become the next special woman in his life?

After breaking up with Culpo, Jonas might want to take a break from fully committed relationships.

Either way, Hudson came out Thursday night in a sexy cut-out jumpsuit showing off her rock-hard abs.
