Kate Hudson and Nick Jonas have not publicly commented on the rumors that they are dating, but the pair was spotted heading towards the Up & Down nightclub in New York this past Thursday.

But perhaps mindful of all the people around, the couple allegedly kept it clean.

"Last night they did not show PDA in the night club," the source told E! News. "They were just friendly. They are not hiding anything, but they also are not publicly talking about their romantic friendship."

For the date with the 23-year-old singer, the 36-year-old actress wore a cutout jumpsuit that gives a peek of her thin waist. Nick Jonas, meanwhile, wore skinny jeans and a red hoodie.

"Even though there are quite a number of years between the two-Hudson is 36 and Jonas is 23-it doesn't seem to bother the two A-listers, as our source says it's 'not a big deal for either of them,'" the article added. "Instead, these two are focusing on having some low-key fun."

The dating rumors involving Kate Hudson and Nick Jonas started last month after they were spotted "all over the place.

"The 2 were all over the place -- together -- this weekend, first at Disney World in Orlando and the next day at brunch in Miami," said TMZ.

"Kate -- who's 36 -- went to Nick's show at the House of Blues in Orlando Saturday night. Oh, right, he's 23. It kinda makes sense. She was probably his jam growing up, and she's still just as hot," it added.

Before the Nick Jonas dating rumors started, Kate Hudson was allegedly hooking up with Coldplay frontman Chris Martin as they scheduled playdates with their respective children in the beach near his home in Malibu.

However, it appears that it's strictly friendship between the two as Chris Martin is now openly dating actress Annabelle Wallis, who the Coldplay frontman was seen engaging on PDA with recently.
