The baby girl, Keeva Jane Denisof, was born on May 23, Hannigan's rep told Us Weekly. "They are all doing well," the rep said.

She joins the couple's 3-year-old daughter Satyana.

Hannigan tweeted the pregnancy news in December, writing, "Yes, I am pregnant! This time it is NOT a food baby, We are beyond happy!"

The "How I Met Your Mother" star told Us Weekly back in 2010, "[Being a mother] has changed me in every way because my life is so much greater. 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."

Hannigan, 38, and Denisof, 46, have been married since 2003.

Earlier this year, Hannigan appeared on the big screen in "American Reunion."
