Kristen Stewart and Nicholas Hoult get cosy at a New York bash!

Los Angeles - Kristen Stewart and Nicholas Hoult were seen cosying up at a bash in New York.

The actress attended a Cinema Society event for her new film Clouds of Sils Maria at Omar's, where she was seen getting very close to Hoult, Jennifer Lawrence's ex-boyfriend.

The pair, who are co-stars in the upcoming Equals, "stuck together throughout the party", according to the New York Post's Page Six Column.

The event, which was also attended by the likes of Patti Smith, Juliette Binoche and Viggo Mortensen, has served to fuel speculation that Stewart, 24, and Hoult, also 24, are dating, despite denials from the actress.

A source close to Stewart - who split from Robert Pattinson, 28, in 2013 after four years of dating - recently told E! News she is enjoying being single.

The source said: "She is in a really, really good place right now. She is really happy with the films she is working on and she is in a great spot in her career."

The source added: "She is finally able to focus on herself and not worry about the nonsense that is out there. This is the best many close to her have seen her in quite a while."
