Emma, 25, and Evan, 29, began dating in 2012, after initially meeting on the set of their film Adult World, but Julia Roberts' niece revealed their romantic relationship didn't start until much later.
"Everyone thought we dated on the movie and we didn't, not for a long time," Emma admitted during a 2014 interview with comedienne Chelsea Handler. "I actually, on the set, was like, 'Oh yeah, we're totally gonna date'. And I would try to, like, flirt with him, which ended up looking like I had something in my eye because I'd be like, 'Hey, what's up?' And he literally didn't speak to me the entire movie. He thought I was so weird."
The on/off couple has had a rocky relationship - Emma was arrested in Canada in the summer of 2013 following an alleged dispute with Evan, but the incident didn't stop the actor from proposing to her the following Christmas (13). The young couple called off the engagement last June (15).
In August (15), it appeared they had rekindled their relationship after they were photographed shopping in Los Angeles, and earlier this year (16), they were spotted kissing in front of a Hollywood restaurant.
