Alyson Hannigan's Maternity Style

Congratulations to Alyson Hannigan and Alexis Denisof, who welcomed daughter Keeva Jane Denisof on May 23, according to People. Keeva joins big sister Satyana in rounding off the Hannigan-Denisof clan of four.

For the past nine months, the second-time mama and actress has wowed us with her ability to transition seamlessly from playground parent to red-carpet glamazon with relative ease. The How I Met Your Mother and American Pie star always puts her role as mom to 3-year-old Satyana first and foremost and does so with style. In honor of the arrival of the family's new addition, we're taking a look back at Hannigan's fashionable pregnancy thus far.
