Last week, Duhamel revealed the sex of the baby during an appearance on Live With Kelly and Michael.

He and his wife announced in February that they are expecting their first child, with Fergie sharing the pregnancy news via Twitter.

"Josh & Me & BABY makes three!!! #mylovelybabybump," the singer tweeted along with a photo of herself and Duhamel as children.

Sounds like somebody's one excited mommy-to-be!
