The actress is currently dating The Crown creator Peter Morgan with the pair thought to have got together in 2016.
Speaking about her romance with Morgan, Anderson told The Times earlier this year how living with her partner would be detrimental to their romance.
She explained to the publication: “If we did, that would be the end of us. It works so well as it is, it feels so special when we do come together.
“And when I am with my kids, I can be completely there for them. It’s exciting.
She went on to say: “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?’”.
Anderson will be making her debut as Prime Minister Margaret Thatcher in The Crown season four which will premiere on Netflix in November this year.
