It's unknown when the actor, 42, popped the question — his reps declined to comment — but wedding invitations have already been sent out for the Aug. 11 ceremony. Rather than traditional wedding gifts, he and Lundberg, 29, have asked guests to donate to her charity, Growing Voices, which is dedicated to giving back to the community. Lundberg, the vice president of the non-profit, is a former ballerina.

He will next be seen opposite Will Ferrell in the political comedy The Campaign.
