Alyson Hannigan has given birth to her second daughter.

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.''
