Natalie Dormer is said to have split from her partner of 11 years, Anthony Byrne.
The 36-year-old recently did an interview with the New Statesman, with the reporter confirming that the pair were no longer together.
The piece cited: “The two met on the set of ‘The Tudors’; they’ve parted ways since promoting the film this summer.”
The split news comes just months after they teamed up to work on the thriller “In Darkness”, which Dormer produced and co-wrote with Byrne.
The duo, who got engaged in 2011 but never set a wedding date, have both previously admitted that working together added stress to their relationship.
The “Game of Thrones” actress told You magazine: “Couples say terrible things to each other that you would never say to your best friend. We learned very quickly that we couldn’t write in the same room.
“Doors got slammed at various points and I wouldn’t necessarily rush into writing with Anthony again.”
Director Byrne added to the Hollywood Reporter, “We learned quickly but we didn’t learn from our mistakes.
“Because we didn’t have an office or anything, we were in our own home writing, and then it would all kick off because we would disagree about something fundamentally or I would be a pain in the a**e.”
ET Canada has reached out to Dormer’s rep for further comments.
