Congratulations are in order for Keri Russell and boyfriend Matthew Rhys! The happy couple welcomed their first child together, People confirms.

This isn’t the actress’s first dip in the baby pond. The 40-year-old beauty is also mom to daughter Willa Lou, 4, and River, 8, both from ex-husband Shane Deary. For Rhys, who co-stars alongside his leading lady in FX's The Americans, this marks his entry into fatherhood. The couple first confirmed they were dating in April 2015, according to People, and their relationship has been nothing but cheery ever since.

For Russell, motherhood is her favorite role to date. “I like working hard, but my life outside of my career is equally important to me,” the former Felicity star told Parade in 2013. “Maybe I’m not ambitious enough, but I’m just as interested in my friends and my relationship with my family." So how has having little ones changed her? “You instantly become less selfish. You can’t be the biggest person in the world anymore—they are. It really grounds you,” she added.

Cheers to the family!
