Jonah Hill dating Isabelle McNally

Jonah Hill has a new leading lady in his life.

The Academy Award-nominated actor is reportedly dating actress Isabelle McNally. The couple was photographed together for the first time back in September.

"It's been going on longer than that, [a] few more months," an insider tells Us Weekly of the relationship.

Hill, 30, and McNally were seen together for the first time while walking their dogs in West Hollywood on September 16. Both actors looked casual as they dressed in workout gear.

Later, on December 30, the couple was seen showing some major PDA while shopping for groceries at Whole Foods.

McNally is known for her appearance in films like Indigo Children and Frances Ha and is currently filming the pilot The Money for HBO.

The 21 Jump Street star previously dated Jordan Klein while in high school, and Justin Hoffman's daughter, Ali Hoffman. The two broke up in September 2012 after a 9-month romance.
