It feels like she's been pregnant forever, but there's a baby on board no more -- Alyson Hannigan has given birth to a baby girl!
The "How I Met Your Mother" star, 38, and her husband Alexis Denisof, 46, welcomed Keeva Jane Denisof on May 23rd, according to Us Weekly.
With the help of a quick Internet search, we found out that "Keeva" is the anglicised version of "Caoimhe" -- a Gaelic name which, according to BehindTheName.com, means "beautiful, gentle, kind."
No other details about the little one have been released.
The former "Buffy the Vampire Slayer" costars -- she played Willow and he was Buffy's mentor Wesley -- have been married since 2003 and have a 3-year-old daughter, Satyana.
Keeva is the first of two "Buffy" babies that are to be born this year -- Sarah Michelle Gellar is pregnant with her and Freddie Prinze Jr.'s second little one as well.
Congratulations to the family!
UPDATE: Alyson just tweeted the first photo of the baby ... well, at least her hand.
