Seth Rogen is getting hitched!

The Funny People star proposed to his longtime girlfriend, writer/actress Lauren Miller last week, Breaking Celebrity News has learned.

Rogen and Miller, both 28, have been dating since 2004. In traditional fashion, Rogen reportedly dropped to one knee and popped the question after the couple returned from a trip to visit family in Boston.

A source said to Life & Style: "He surprised her with the proposal. She'd started giving up hope that he would ever pop the question."
