The `American Reunion` actress and her husband, Alexis Denisof, welcomed Keeva Jane into the world on May 23.

A representative of the couple told US Weekly magazine: "They are all doing well."

Keeva Jane joins the couple`s other daughter, three-year-old Satyana.

Alyson had referred to her pregnancy a few times on twitter, shortly after fellow celebrity Jessica Simpson gave birth last month she wrote: "Does this mean I now have the biggest bump?"

The 38-year-old star also recently joked that she was "ready to pop" and said: "I could be doing the math wrong but I think I`m in my 5th trimester (sic)."

`How I Met Your Mother` star Alyson - who married Alexis in 2003 - talked about how her life was changed by becoming a mother for the first time in 2010.

She said: "It 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. Satyana is just the greatest baby."
