Seth Rogen Engaged to Girlfriend Lauren MillerSeth Rogen is officially off the market after proposing to longtime girlfriend Lauren Miller. Rogen told Conan O'Brien that despite his romantic intentions, he ended up popping the question to Miller when she was topless in their bedroom.

"She was in our closet, changing, and she was literally only in her underpants. I had already kind of started [to propose]. ... I didn't picture it like this, and I know she didn't picture it like this."

PEOPLE reports that Rogen admitted to being excited about planning the wedding, an interest that came as a surprise to him.
