'The Green Hornet' star Seth Rogen is engaged to longtime girlfriend, Lauren Miller, Life and Style exclusively reports. The funnyman asked the writer-actress to marry him last week. Rogen and Miller, both 28, have been dating since 2004.

"He surprised her with the proposal," a friend of Rogen's tells Life & Style. "She'd started giving up hope that he would ever pop the question."

The former 'Freaks and Geeks' actor proposed to his ladylove after returning home from a trip visiting family in Boston. "Her family adores him; everyone is thrilled to plan a wedding," the source adds.

Rogen has made his feelings about his future wife pretty clear, previously stating, "I have a girlfriend who is far prettier than I should have."
