It's official: The Office beauty Ellie Kemper is engaged!

The 31-year-old redhead confirmed the great news Wednesday to Conan O'Brien, who has his own history with her husband-to-be.

"The guy you got engaged to is a very talented writer who worked for me for many, many, many years -- Michael Koman," O'Brien, 48, joked.

She told O'Brien, "My family likes him a lot. They've met him many times... my parents are very warm, welcoming people to begin with, but also, Michael's a delight -- so of course, they like him a lot.
