Seth Rogen embarrassed by proposal

Seth Rogen proposed to his girlfriend when she was wearing just her underpants.

The 'Green Hornet' actor had planned an elaborate proposal, but decided to pop the question to his long-time love Lauren Miller right then in their home in case he lost the ring, much to the unhappiness of his future father-in-law.

Seth - who proposed to his girlfriend of six years last September - told US TV talk show host Jay Leno: "She happened to only be in her underpants. I didn't think I'd be telling it so much when I did it. Her parents have heard me tell the story, and her dad's not happy about it.

"He asked 'You couldn't have waited until she had a shirt on at all? That wasn't an option?' "

Earlier this week the funnyman confessed that since he proposed Lauren has been doing all the wedding planning -and feels like he's "the last piece of the puzzle".

He said: "I'm around for it. My girlfriend has a very vested interest. I think she's been planning this for years. I'm the last piece of the puzzle. I'm excited. It's going to be lovely."
