American Pie star Jason Biggs is engaged to his girlfriend, actress Jenny Mollen, a rep for the actor confirms to PEOPLE.
The couple looked cozy at the premiere of 29-year-old Biggs’s new comedy Over Her Dead Body Tuesday night, and Mollen, 28, was sporting a impressive ring.
The pair met on the 2007 set of My Best Friend’s Girl, which is set for release this fall.
