Keri Russell is a mom.

The 31-year-old actress welcomed her first child, a boy named River Russell Deary, on June 9 in New York, her publicist, Jill Fritzo, said Tuesday.

Russell married Shane Deary, a contractor, in Manhattan on Valentine's Day. The couple became engaged last year.

She stars as a woman grappling with an unexpected pregnancy in the independent romantic comedy "Waitress," which has been warmly received by critics.

Russell portrayed college student Felicity Porter in the TV series "Felicity" for four years. The series ended in 2002.

She also starred in the films "Mission: Impossible III" and "The Upside of Anger," and the TV miniseries "Into the West."
