Seth Rogen & Lauren Miller are Engaged!

Actor Seth Rogen and his longtime girlfriend/actress Lauren Miller are now engaged and he popped up the question after they returned from a family visit in Boston last week.

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

“Her family adores him, everyone is thrilled to plan a wedding,” the friend adds. As for Seth, there’s no doubt as to how he feels about Lauren: “I have a girlfriend who is far prettier than I should have,” he’s said.

The two have been dating for more than six years since 2004.
