She and her husband, actor Alexis Denisof, welcomed a daughter on March 24 -- the same day as Hannigan's 35th birthday.

Hannigan's rep told People, "They're very excited, and mom and baby are doing great." The baby's name is Satyana Denisof, and she's the first child for this couple, who met on the set of Buffy the Vampire Slayer and were married in 2003.

Hannigan appeared on the Ellen Degeneres Show in January, where she refused to reveal the gender of the baby (she and Denisof knew but didn't want the rest of the world in on the secret). She also talked a little bit about her pregnancy, including a condition she refers to as "pregnancy brain," which causes her to feel "like a Koala bear where I'm slightly stoned all the time and say the wrong word," and also an intense craving for ginger ale.

Watch the clip below to see Ellen try to trick Alyson into divulging the baby's gender.
