Kate Hudson partied with Nick Jonas in New York City last night (15.10.15).
The 36-year-old actress and the 'Jealous' hitmaker, 23, who sparked dating rumours last month, went clubbing together at Up & Down in the Meatpacking District, but were careful not to get too close.
An eyewitness said: "Last night they did not show PDA in the night club. They were just friendly. They are not hiding anything, but they also are not publicly talking about their romantic friendship."
The pair, who first met while they were dating other people last year and were "reintroduced" by Kate's brother Oliver Hudson over the summer, only recently sparked rumours of a romance, but have been secretly "hanging out casually over the past two or three months."
The source told E! News: "Nick loves how fun and easygoing Kate is. Kate is just enjoying herself now and not taking anything too seriously.
"She is having a great time and likes hanging with Nick. She feels great, and when they are in the same city they hang out."
Nick stayed tight-lipped when recently asked about the 'Almost Famous' star, who has sons Ryder, 11, and Bingham, four, from previous relationships, and his brother Joe Jonas also claims he is being kept in the dark.
Asked about the 'Chains' hitmaker's new romance, the 26-year-old star, who is dating model Gigi Hadid, told UsMagazine.com: "I have no idea, I don't know. Um, but. I guess you'll have to ask Nick. I wouldn't even know to be honest. I don't know."
