Keri Russell and Matthew Rhys, who costar opposite one another on FX’s The Americans, have welcomed their first child together.

Keri Russell & Matthew Rhys Welcome Baby

Russell, 40, gave birth to her first child with Rhys, 41, last week, People magazine confirmed. The baby is the first child for Rhys and the third for Russell, who has son River, 8, and daughter Willa, 4, with her ex-husband Shane Deary.

“Keri and Matt both look overjoyed and are over the moon to be new parents,” a source told Us Weekly. “They are always snapping pictures of the baby, and family and friends have been sending gifts.”

The source added, “Keri’s mother and brother have been staying with them for the last week, spending all their time doting over the baby.”

It was confirmed back in January that the pair were expecting a baby after rumors started to swirl earlier in the month. At the Winter Television Critics Association press tour, Russell and Rhys’ The Americans cast mate Noah Emmerich acknowledged that the two were in fact expecting, as did executive producer Joel Fields, while Rhys replied with a joke.

Russell and Rhys went public with their romance in April 2014 after months of speculation about their relationship.
