Keri Russell and Matthew Rhys have lots to celebrate!
After it was announced that their FX show, The Americans, has been renewed for a final two seasons, Us Weeklyis reporting that the 40-year-old actress gave birth to the couple's first child together some time last week. ET has reached out to the stars' reps for comment.
This is the first child for Rhys, 41, while Russell is already a mom to River, 8, and Willa, 4, with her ex-husband, Shane Deary. The two separated in 2013 after seven years of marriage.

In January, Rhys and Russell's Americans' co-star, Noah Emmerich, confirmed the actress' pregnancy to ET. "First of all, Keri's really petite. It looks like she swallowed a large pea," he joked of her baby bump. "But yes, we shoot around it."
