It has been over eight years since viewers saw Rhys and Russell as spies on the FX thriller The Americans and over five years as parents.
Naturally, fans have shown great curiosity in knowing if Russell is Rhys' wife. Some believe they are married, while some argue they are just in a living relationship.
Having said that, news outlets such as Dailymail have referred to them as a married couple.
In December 2020, the tabloid reported that "Matthew Rhys and wife Keri Russell are teaming up for a new project." The pair was working on FX drama Wyrd.
But again, Rhys and Russell have not confirmed anything about tying the knot.
