Jennifer Garner has said she won’t be having any more children.

The actress, 40, is already a mum-of-three with husband Ben Affleck, to six-year-old Violet, three-year-old Seraphina and seven-month-old son Samuel.

Asked if she wanted to expand the brood, the Juno star told The Ellen DeGeneres Show: “No… I plan to be done.

But she joked: “But my husband is kind of a ‘wonder sperm’ kind of guy.”

She said actor Ben was great with the kids.

“You know, his girls are so into him … He kind of excels at playing baby doll!”

She joked that she had so many children that “I can’t get their names straight…”

Ben and Jennifer married in 2005 after meeting on the set of the movie Daredevil, which was based on a comic book series.
