Alyson Hannigan Welcomes Daughter Keeva Jane!

Welcome to Hollywood, Keeva!

Alyson Hannigan and husband Alexis Denisof welcomed their second daughter, Keeva Jane Denisof, May 23, her rep tells Us Weekly exclusively.

Little Keeva joins big sister Satyana, 3. "They are all doing well," the rep adds. Us was first to break news of Hannigan's second pregnancy in mid-December.

Last month, the How I Met Your Mother actress, 38, was among the many Hollywood moms congratulating (via Twitter) Jessica Simpson on the birth of her daughter Maxwell Drew. Joked Hannigan: "Does this mean I now have the biggest bump?"  (The star also cracked that people assumed she was "ready to pop" as early as April.)

Thank You!

The Buffy the Vampire Slayer alum wed Denisof, 46 (who starred on Buffy spinoff Angel) in October 2003.

"[Being a mother] has changed me in every way because my life is so much greater," Hannigan told Us in May 2010. "It filled a void I never knew was there — it's the most amazing experience of my life. I just feel so blessed to get to be on this journey, to be a mommy. [Satyana] is just the greatest baby.
