Keri Russell is reportedly expecting a baby with her boyfriend, and co-star of ‘The Americans’, Matthew Rhys.

The couple began dating when they met on the set of the FX spy drama in 2013, and a report by Us Weekly on Wednesday suggested that they were expecting their first child together. “Keri is more than four months along. It’s so exciting for them,” a source told the publication.

Russell, 39 years old and a former star of ‘Felicity’ and of movies like Dawn of the Planet of the Apes, has two children (daughter Willa, 4, and son River, 8) from her seven-year marriage to ex-husband Shane Deary, which ended in 2013.

She and her current partner Rhys, 41, portray an on-screen couple in ‘The Americans’, playing married Russian spies living in 1980s Washington. They’re often spotted out and about in New York with her children, and season four of the critically acclaimed show is being filmed at the moment in Brooklyn.

“They are always together and love roaming around New York,” a second source revealed. “Matthew is really in love. They feel they should have always been together.”

However, their on-screen relationship is very much unlike their real life one. “It's not this big, sweeping romantic movie where you have to be so in love and so beautiful and so sexy,” Russell said ahead of the third season of ‘The Americans’. “You're usually using the sexuality, at least in the spy end of it, to get something. So there is kind of a freedom in that, because it's kind of messier or more direct than that.”

Russell was pregnant with her daughter during filming of Austenland, and spoke at the time about some of the positive side-effects she felt about being pregnant. “I absolutely loved being voluptuous,” she told USA Today in an interview. “That's not a word that I have ever had anyone describe me as – voluptuous. I will never be voluptuous except when I'm pregnant. It was amazing.”
