The TV series, currently in its fourth run, has been renewed for another two years to wrap up the storyline.

"It's hard to believe we're heading into the final stretch on The Americans, and we're so grateful to know we'll be telling the story to its conclusion," show bosses Joel Fields and Joe Weisberg wrote in a statement.

"The best part of the last four years has been the intensive and fruitful collaboration with all of the people who make this show... It's a lot of people putting their hearts and souls into The Americans, at this point for a lot of years. We're looking forward to the final two."

The Americans follows Rhys and Russell's married Soviet spy characters as they gather information while living in the U.S. during the Cold War. The show also features Noah Emmerich, Richard Thomas, and Frank Langella.

Rhys and Russell will always have fond memories of the drama after falling in love on the set.

The couple began dating in 2013, following the breakdown of Russell's marriage to Shane Deary - the father of her two young kids.

Russell and Rhys are now expecting their first child together this summer (16).
