The Crown star Claire Foy and actor Stephen Campbell Moore have officially announced being separated after four years of marriage.

The two thespians have a 2-year-old daughter together, Ivy Rose.

The Queen Splits With Husband

While news only just broke of the break-up between Foy and Moore, the couple revealed that they have actually been living apart for a while now.

"We have separated and have been for some time," an official statement sent to the Mirror read. "We do however continue as great friends with the utmost respect for one another."

Foy, 33, and Moore, 38, met while filming their film Season of the Witch in 2011. The couple said their vows in 2014.

One of the couple's friends told The Sun that the split was a surprise even to some of the people surrounding them.

"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," the pal says, adding that it's been a sad time for Foy, Moore, and their families. The couple apparently agreed that the relationship wasn't working anymore and separation is the best choice for everyone involved.

The last time Foy and Moore attended a public event together was in May 2016.

Highs, Lows Together

Their four years as a married couple mean they've been through a number of successes and challenges together.

Foy has earned industry renown for her portrayal of Queen Elizabeth II in Netflix period drama The Crown. She even nabbed the trophy for Outstanding Female Actor in a Drama Series at the 2018 SAG Awards.

At the end of last January, an interview with The Sun revealed that Moore was diagnosed with a benign tumor in the brain back in 2016. The tumor was found in the pituitary gland at the base of his brain, known to control metabolism. It was removed successfully.

"You realize you're not the most important person in that process, and everybody who loves you goes through far worse," Moore said.

Foy has been through similar challenges in the past, being ill-ridden as a child with a benign tumor in her eye when she was 17. It was treated without invasive surgery, but her steroids caused weight gain and skin problems for a while.

The award-winning actress has already stepped away from her acclaimed role in The Crown after two seasons. The older Queen Elizabeth II will be portrayed by Olivia Colman.
