Keri Russell is expecting a baby with her co-star from The Americans, Matthew Rhys. This is the child for Rhys, 41, and the third for Russell, 39, who is already mom to daughter Willa Lou, 3, and son River, 7 1/2. After months of rumors, the couple’s relationship was confirmed in April 2014. The former Felicity star says she changed when she became a mother: “You instantly become less selfish. You can’t be the biggest person in the world anymore—they are. It really grounds you,” she told Parade.
