Alyson Hannigan

Arrival date: March 24, Alyson's birthday
It's... a girl! Her name is Satyana.
Proud papa: Alyson's actor hubby, Alexis Denisof.
And baby makes... three. This is the first child for the How I Met Your Mother actress and her husband. The couple met on the set of Buffy the Vampire Slayer.
Birth announcement: How I Met Your Mother fans watched Alyson's baby bump grow, though the show's producers did their best to keep her belly hidden with every prop imaginable. Alyson's rep confirmed Satyana's "legendary" birth, saying, "They're very excited, and mom and baby are doing great."
