What's hotter than watch Adam Levine? Watching Adam Levine on the big screen. He co-stars in 'Begin Again' with Keira Knightley and Mark Ruffalo.

Levine plays Dave, Gretta's (Keira Knightley) boyfriend. The two are college sweethearts and songwriting partners. They head for New York where he lands a record deal. Dave's new-found fame tempts him to stray, and leaves Gretta on her own.  Sounds pretty close to real life, doesn't it?

Dan (Mark Ruffalo), a disgraced record-label exec, stumbles upon Keira/Gretta performing and is captivated by her raw talent.

Begin Again is in theaters July 4th.
