Sophie Cookson has revealed that her mother, Marie, is receiving end-of-life care in hospital and that the actress has spent more than two weeks at her bedside.

In an Instagram post on Wednesday, the 35-year-old Kingsman star wrote, "I’ve been in hospital for over two weeks as my mum receives end of life care. It can be maddening, scary and jarringly beautiful." She added that she would read messages from others going through similar experiences, saying, "No one needs to feel alone."

Cookson did not disclose further medical details about her mother’s condition. In the post she asked followers who were facing comparable situations to share their experiences, writing that "maybe through sharing stories, this inevitable part of life can feel less daunting." She said she could not promise to reply to everyone but promised to read messages sent to her.

The Sussex-born actress has documented parts of the family’s recent summer in Europe on social media, posting photographs of her mother enjoying time with family members and with Cookson’s five-year-old daughter. In August she shared an image of her mother gazing across a hilly landscape and wrote, "Summer is fading and the melancholia of late August is ripe, but there is so much to be grateful for. Make sure the people you love know it and don’t sweat the small stuff. At the end it’s irrelevant." Another post showed Marie smiling at a flower market.

Cookson rose to prominence in the 2014 film Kingsman: The Secret Service. She has been in a relationship with actor Stephen Campbell Moore, 45, since 2018; the couple share a daughter born in 2019. Campbell Moore previously was married to actor Claire Foy, with whom he has a daughter.

Four months before the Instagram update about her mother, Cookson broke a 16-month social media silence to write about a personal "radical reset." In that earlier post she said she had stopped drinking, trained to become a yoga instructor and found the experience transformative. She described the change as a response to feeling she had been "always less" and wrote that the practice brought unexpected "wisdom and unbound kindness."

Cookson’s Instagram message about her mother drew public attention for its candid description of the emotional complexities of being present during end-of-life care. She did not timetable any public appearances or professional commitments in the post, and no additional information about her mother’s illness has been made available.
