'The Crown' star Claire Foy announces separation from husband Stephen Campbell Moore

The Crown star Claire Foy has announced separation from her husband Stephen Campbell Moore.

The couple had married in 2015 and together have a daughter, Ivy Rose, who was born in March 2015. They had met on the set of the film Season of the Witch in 2011.

Foy, 33, in a statement to The Sun, revealed that she had been separated from Moore for quite "some time".

"We have separated and have been for some time. We do however continue as great friends with the utmost respect for one another," Foy said.

In late 2016, Moore, 38, had revealed that he was diagnosed with the benign tumour on his pituitary gland, at the base of the brain. He underwent a life-saving surgery in July last year.

A source close to the couple told the Sun, "After seven years together this came as a real shock to many of their friends, but they're lovely people and are determined to keep everything civilised."

"They've just decided that unfortunately their relationship simply wasn't working and that this would be for the best," it added.

Foy will be next seen in the First Man, co-starring Ryan Gosling, and will also play Lisbeth Salander in the upcoming film The Girl in the Spider's Web.
