Kate Hudson is rumored to be dating the 23-year-old Nick Jonas, who is 13 years her junior. However, the actress was seen getting intimate with another man, her agent Michael Kives, after partying at the Up & Down nightclub in New York on Monday night.

A photo shared by Mail Online shows the mother-of-two at the back seat of her car with Kives. The pair seemed to be engaged in a serious conversation with their heads very close to each other. Hudson's agent also looked as if he is about to kiss her. They seemed oblivious to the other people inside the car as they only have eyes for each other.

Another picture shows Hudson giggling probably at what Kives said. The blurred image shows the actress laughing with her mouth open while Kives settled for a cheeky grin, looking rather amused himself. Kives was also photographed whispering something into Hudson's ears that made Hudson grin.

According to Mail Online, Kives and Hudson were hanging out together around Tribeca after the premiere of her new movie "Rock The Kasbah." They were also spotted holding hands, with the "Almost Famous" star still dressed in the gold dress she wore to the premiere. The actress changed to the sleek white ensemble before heading to Up & Down nightclub with Kives, who is said to be her long-time friend too.

Early Sunday morning the 36-year-old was also seen kissing another mystery man. It's uncertain if it's also Kives in the photos shared by Radar Online since his face is obscured from the camera. In the photos the man is leaning against a steel pole while Hudson tiptoes to kiss his cheek.

Hudson has been frequenting the posh nightclub in NYC lately. She was also there at the nightspot on Thursday, Oct. 15 at the same time her rumored boyfriend Nick Jonas was spotted entering the scene. Hudson was dressed in a sexy black dress while Nick tried to go incognito by covering his head with the hood of his jacket.

The actress has been attached to several men since her split from Chris Robinson and Muse singer Matthew Bellamy. Hudson has been linked to "Dancing with the Stars" alum Derek Hough and lately with the "Jealous" singer. But Hudson and the younger Jonas brother has yet to comment on the dating speculations. Joe had told US Weekly that he has "no idea" if his brother and Hudson are together.
