The CW's new spinoff series "The Originals" may be about Klaus and his unborn baby, but in real life, it's star Daniel Gillies' turn to be a father.

"The Originals" star, 37, has welcomed a baby girl with his wife Rachael Leigh Cook, Gillies confirmed on Twitter on Sunday (Sept. 29). This is the first child for the "She's All That" star, 33, and Gillies. 

Gillies and Cook were married in August 2004. They first announced they were expecting a baby back in May, when Cook could no longer hide her growing baby bump.

Congratulations to the new parents.
