'The Late Late Show' host Craig Ferguson and wife Megan Wallace are expecting a baby, the comedian revealed on Twitter Wednesday morning.

"Holy crackers! Mrs F is pregnant. How did that happen? ...oh yeah I know how. Another Ferguson arrives in 2011. The world trembles," Ferguson Tweeted.

Ferguson and his art dealer wife got married in a secret wedding in December 2008 over the holidays. "The wedding took place in Vermont, where they have legalized gay civil unions -- and I married a woman," Ferguson revealed on his show. Talking about the ceremony, he joked at the time, "I am European, so I was both the groom and the maid of honor."
