The Hunger Games actress is dating director Darren Aronofsky, a source close to Lawrence tells PEOPLE.

“They’ve been hanging out and are casually dating,” says the Lawrence pal.

Over the summer, Lawrence, 26, and Aronofsky, 47, collaborated on a still-untitled project together starring the Oscar-winning actress, Ed Harris and Javier Bardem. They were also photographed together in August enjoying lunch at a cafe.

Currently in post-production, the movie is directed and written by Aronofsky and focuses on a couple whose relationship is disrupted when unwanted guests enter their lives.

Earlier this year, the star told Harper’s Bazaar she doesn’t have a specific “type” when it comes to men. “Patterns are the work of the devil,” said Lawrence. “If I think about all of my ex-boyfriends, they are all so uncomparable.”

Lawrence — who stepped out Tuesday night to support her friend Emma Stone at a La La Land screening — was last romantically linked to Coldplay frontman Chris Martin.

Aronofsky shares a 10-year-old son, Henry, with ex Rachel Weisz.
