Carey Mulligan and Marcus Mumford have been married for over 10 years. The actress and musician reportedly met at camp as pre-teens and became pen pals to keep in touch. Years later, they reconnected as adults and began dating. Just a few months later, Mulligan and Mumford were engaged and later married on a farm in England. The couple welcomed their first child, daughter Evelyn, in 2015. A son named Wilfred followed two years later and Mulligan and Mumford completed their family with the birth of their second daughter in 2023. While they’re known to keep their relationship private, the couple don't shy away from supporting each other's work. In March 2025, Mulligan appeared on Jimmy Kimmel Live! and shared that she’s listened to all of her husband’s demos and musical work. However, she joked that he hasn’t seen all of her movies. “He’s seen some of them,” Mulligan said, before joking that she’s “okay” with it since she’s starred in quite a few. Here’s everything to know about Carey Mulligan and Marcus Mumford’s relationship, including their summer camp connection. They were summer camp pen pals years before marrying During a 2024 appearance on Good Morning Britain, Mulligan shared that she met Mumford when he was 10 and she was 12 while at a summer camp. The two stayed connected by writing letters to each other when camp ended. “We became pen pals after and that’s how we kept in touch, we didn’t have phones,” she said on the show. “We used to fax a bit when fax machines were cool. We need to get kids doing the pen pal thing again. It’s a good thing.” However, Mulligan and Mumford lost touch for about 10 years before finding each other again on Facebook. In December 2023, the actress shared that her husband wasn’t “boyfriend material” when they were kids. “I wrote in my diary that he was the nicest, the kindest person I’d ever met, and I gave him 9 ½ out of 10,” she said on the SmartLess podcast. “I also wrote that he definitely wasn’t boyfriend material. Not that I’d ever had a boyfriend at that time! But I decided that he was not it.” Mumford and Mulligan had chemistry after reconnecting It seems like music helped rekindle the chemistry between Mumford and Mulligan. In February 2011, Mulligan was seen at a private Mumford & Sons concert held in a basement in Nashville, according to Rolling Stone. Later that year, they were spotted at another one of Mumford’s concerts in St. Magnus Cathedral in the U.K. The two “were kissing and cuddling in public,” and “were clearly very fond of each other. They were very, very affectionate to one another,” a concertgoer told PEOPLE. Shortly after, the couple spent time together in London, where Mumford lived, and Buckinghamshire, England. After just five months of dating, Mumford proposed to Mulligan in August 2011 while they were on vacation in Somerset, England. They married in 2012 On April 21, 2012, the couple’s family and friends gathered together in Somerset, England, in a charming barn to watch Mumford and Mulligan exchange vows. In attendance were fellow celebrities like Sienna Miller, Jake Gyllenhaal and Colin Firth. They sent each other love letters when Mumford was on tour In 2013, the “Grace” singer was on tour and Mulligan’s career was in full swing. With so much time apart, the two returned to their pen pal roots. “Love letters are becoming a lost art form, which is very sad,” Mulligan reportedly told The Telegraph in May 2013. “To have a love letter from someone, to hold it in your hand and know you can keep it for your whole life, that’s an amazing thing.” They prefer to keep their relationship out of the spotlight With such a public life, the Great Gatsby actress told Vogue in 2015 that she prefers to keep her relationship out of the spotlight. “Marcus is the only thing that’s mine that I can keep totally away, so I try to,” Mulligan said. Because they both have careers that can get pretty hectic, the couple decided to live away from the spotlight and have a home in the country. They share three children Three years after tying the knot, Mulligan and Mumford welcomed their first child together, a daughter named Evelyn Grace. “Carey has given birth to a healthy and happy baby,” a source told PEOPLE at the time. “She is just enjoying this time with her family and close friends.” Mulligan and Mumford’s family expanded in August 2017 when they welcomed their son Wilfred. The couple grew their family once again with the birth of their third child, a daughter, in 2023. They were locked down at home together in 2020 During the COVID-19 pandemic, Mumford and Mulligan had to navigate their busy work schedules while hunkered down at home. The “I Will Wait” singer gave a virtual performance on The Tonight Show Starring Jimmy Fallon — but Mumford had some distractions around him. “Hi Jimmy, my kids are screaming and my dog is barking and my wife is directing,” he joked. A year later, Mulligan hosted Saturday Night Live for the first time and joked that spending “the last year quarantining in the English countryside with my husband and two small children” seemed like “the beginning of most horror movies.” Her husband proceeded to crash her opening monologue. “It’s me, Marcus Mumford, from the band Mumford & Sons,” he said, waving from his seat in the audience. “I left the kids with the Sons ... Do you know if they booked a musical guest for tonight?” He proceeded to pull out his acoustic guitar as his wife jokingly begged him to stop singing. They make their marriage a priority In a 2022 cover story with GQ, Mumford shared that he and Mulligan focused on making their marriage “the priority” right after they said “I do.” “We said, ‘The odds are stacked against us. Let’s make that our great work and everything else can come from that, right?’ ” he told the publication. “The reason I think people don’t stay married is because they don’t realize how much work it takes.” They’ve worked on projects together While their careers are vastly different, Mulligan and Mumford have collaborated a few times throughout their relationship. Mulligan starred as Jean Berkey in the film Inside Llewyn Davis while Mumford voiced a character and co-produced the movie’s soundtrack. The two also performed at the concert “Another Day, Another Time: Celebrating the Music of Inside Llewyn Davis,” in New York in September 2013. Mulligan and Mumford sang several songs from the movie alongside the cast members, per The New York Times. In July 2022, Mumford released a music video for his song “Cannibal,” which was directed by Steven Spielberg. The singer posted about the experience on his Instagram, thanking those who worked on the video, noting that Mulligan contributed to the sound and his outfit. He shared a series of pictures, including one of the couple with the full cast and crew of the music video. “I’ve been overwhelmed by the support of the people around me to bring this music to you, and I cannot hope to express all of my gratitude,” Mumford wrote in the caption. “When people get it, it blows my mind.” They’re supportive of each other's careers Whether it’s for music or movies, Mulligan and Mumford frequently attend award shows together and support each other on the red carpet. They first stepped out on the red carpet together in 2013 at the Grammys. Mumford performed with his band and won Album of the Year for Babel. Mulligan proudly cheered her husband on the whole night, hugging him in the audience to celebrate the win. Mumford returned the favor by accompanying Mulligan to the Oscars in 2021, where she was nominated for Best Actress for her role in Promising Young Woman. The couple also got dolled up to attend the Met Gala together in 2022. Two years later, they attended the Golden Globes together as Mulligan was up for the Best Actress award for her role in Maestro. While she didn’t win, Mumford made the night special for his wife. He shared a TikTok of himself carrying her around backstage of the show, with an acoustic version of Ryan Gosling’s I’m Just Ken from the Barbie movie playing in the background.
