Alyson Hannigan has welcomed her second child.

The How I Met Your Mother star and husband Alexis Denisof are now the proud parents of another girl who they have named, Keeva Jane Denisof.

The bundle of joy joins three-year-old big sister Satyana.

"They are all doing well," a rep told Us Weekly who confirmed the actress had the child on May 23.

Alyson and Alexis have been married for nearly nine years.

"[Being a mother] has changed me in every way because my life is so much greater," Alyson gushed about parenthood.

"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."
