The actress, 33, best known for her role as Queen Elizabeth II in the Netflix Royal drama, and her partner, 38, confirmed their four-year marriage is over in a joint statement released on Thursday evening.
The couple, who originally met while working on 2011 film Season Of The Witch, revealed they had parted ways long before the news was made public.
The Crown star Claire Foy has announced her separation from husband Stephen Campbell Moore, months after he underwent crucial surgery to remove a brain tumour.
She said : ‘We have separated and have been for some time,’ they said. 'We do however continue as great friends with the utmost respect for one another.'
