Gillian Anderson has added another man to her ex file.
The actress and beau of four years, Peter Morgan, have split up, according to a new report by Page Six. The split comes after Gillian, 52, portrayed Prime Minister Margaret Thatcher on "The Crown," a series that Peter created.
The breakup was amicable, the report adds.
The former "X-Files" star and the British screenwriter began dating in 2016. The romance followed her nine-year relationship with "The Fall" star Mark Griffiths.
Of Gillian and Peter's union, The Daily Mail said the relationship has just "run its course," and they intend to "remain great friends." Over the course of the four years, the duo never lived together, which she brought up in an interview earlier this year.
"My partner and I don't live together. If we did, that would be the end of us," she told The Times in January. "It works so well as it is. It feels so special when we do come together."
"We choose when to be together. There is nothing locking us in, nothing that brings up that fear of 'Oh gosh, I can't leave because what will happen to the house, how will we separate?' I start to miss the person I want to be with, which is a lovely feeling," she continued. "And it is so huge for me to be able to see a pair of trousers left lying on the floor at my partner's house and to step over them and not feel it is my job to do something about it!"
Gillian was married twice before linking up with Peter.
