Nick Jonas Opens up About Kate Hudson Romance Rumors

Kate Hudson went party hopping on Monday evening, and this time her rumored beau, Nick Jonas, was nowhere to be found.

The 36-year-old actress was first seen last night at the New York City premiere of Rock The Kasbah, wearing a show-stopping sequin, curve-hugging gown. Somewhere between posing at the premiere and showing up for the 2015 Angel Ball after party at the Up and Down club, Hudson did a wardrobe change and again stunned in an all-white outfit.

But her envy-worthy ensembles weren't what had the blogosphere talking. Upon leaving the nighclub, Hudson was seen cuddling up to a mystery man in the backseat of a car.

While the man's identity has yet to be officially confirmed, it appears to be her agent and good friend, Michael Kives. At the premiere, the two were seen holding hands.

As other photos have shown in the past, they appear to have an affectionate friendship, and have never been more than just pals.

ET has reached out to Hudson's rep for comment.

Jonas was not party hopping with his rumored new fling, because he had business to attend to in Los Angeles. The 23-year-old posed for pics at the Paley Center for Media in Beverly Hills, California on Monday night in promotion of his DirecTV show, Kingdom.

It was, however, only a few days ago that Hudson and Jonas were out and about in New York City. The two were both spotted at the Industry Club last Thursday for Demi Lovato's launch party of her new single.

The outing definitely fueled romance rumors, but when ET spoke with Jonas, he insisted that he was still on the market. "I'm 23, single and loving life," he said. "And in a 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."
