Celebrity Couples Who Started Their Relationships as Affairs
Sutton Foster and Hugh Jackman started dating when they starred together on Broadway’s Music Man back in 2021. At the time, Jackman was still married to Deborra-Lee Furness, and Foster was married to Ted Griffin. Ariana Grande and her boyfriend Ethan Slater met while working on Wicked together, which began filming in December 2022. LeAnn Rimes and Eddie Cibrian got together in 2009, despite both of them being married at the time. Alicia Keys and Swizz Beatz reconnected in July 2023, months after he married Swizz’s ex-wife, Mashonda Beatz, whom he was dating at the same time. The two are now happily married and have a son, born in August 2022. The couple also have a daughter, Lizzie, who was born in March 2023 and a son with ex-husband Dalton Gomez, who died in June 2023. They also have an 11-year-old son, James, who they have together.
And while we’ll always have a soft spot for celeb love, especially when they gush about each other in candid interviews, celebrities have also been quite messy in the past, too. In fact, some beloved Hollywood couples began their relationships as full-on affairs. Whether one or both of them were married when they first met, some of these love stories have been nothing short of unconventional.
In early 2025, Sutton Foster and Hugh Jackman were the latest couple to seemingly confirm cheating rumors. According to several reports, the two started dating when they starred together on Broadway’s Music Man back in 2021. The two were married at the time, but have since divorced their exes.

After word got out, they split from their partners and ended up marrying each other in 2011.
“It was so public,” Glanville said of their affair in an op-ed to The Sun. “Everyone felt sorry for me and wanted to hug me. But I wanted to punch everyone in the face. I couldn’t turn on the TV without seeing something about them.”
“LeAnn had taken over my life and I didn’t have a voice anymore,” she continued. “I did not want my kids around her. She’d got my husband and she was not getting my children.”

Angelina Jolie and Brad Pitt met in the summer of 2004 on the set of Mr. and Mrs. Smith, the spy thriller on which they’ve since admitted they both fell in love — if not quite admitting to an affair. At the time, Pitt was famously married to Jennifer Aniston, who went on to file for divorce from Pitt in March 2005.
Just four months later, Pitt and Jolie were granted a spread in W magazine showing off their “domestic bliss,” with photos taken in March.
Jolie had this to say about how they fell in love in 2006. “Because of the film, we ended up being brought together to do all these crazy things, and I think we found this strange friendship and partnership that kind of just suddenly happened,” she told Vogue. “I think a few months in I realized, ‘God, I can’t wait to get to work.’ … Anything we had to do with each other, we just found a lot of joy in it together and a lot of real teamwork. We just became kind of a pair.”

King Charles & Queen Camilla
King Charles & Queen Camilla
One of the most publicized affairs in royal family history involved King Charles, Queen Camilla, and the late Princess Diana. Per reports, Charles was unfaithful throughout their marriage, which started in 1981.
In her iconic Panorama interview with journalist Martin Bashir in 1995, Diana confirmed their affair.
“What effect did [their affair] have on you?” Bashir asked the late Princess of Wales. “Pretty devastating,” she replied. “Rampant bulimia, if you can have rampant bulimia, and just a feeling of being no good at anything and being useless and hopeless and failed in every direction.”

“And with a husband who was having a relationship with somebody else?” Bashir added. “With a husband who loved someone else, yes,” she replied. “You really thought that?” Bashir asked. “I didn’t think that,” the royal stated. “I knew it.”
Later on, Bashir asked if Queen Camilla’s affair with her ex-husband was the reason for their split. “Well, there were three of us in this marriage, so it was a bit crowded,” she famously replied.
Charles and Diana, who had been separated since 1992, divorced in 1996. Charles and Camilla went on to marry in 2005, eight years after Diana’s tragic passing.

And — oh, yeah — I had a husband too,” Spelling wrote, per Us Weekly, before revealing that they spent the night together at a hotel. “The following day, when I woke up next to Dean, I had no regrets. Something was really wrong with my marriage. Not only because I slept with this guy — though that certainly wasn’t a positive sign — but because I didn’t regret it.”
Spelling and McDermott married a year later 2006 and welcomed five kids throughout their marriage.
McDermott announced their separation in June 2023 and Spelling filed for divorce in March 2024.

“I left our home to work on a movie, and while I was away, my boyfriend got married, and I’ve never heard from him again,” Dern told ABC.
“It’s like a sudden death. For no one has there been any closure or clarity,” she said.

At the time they met in 2014, Big Sean was engaged to the late Naya Rivera.
In her 2016 memoir, Sorry Not Sorry: Dreams, Mistakes, and Growing Up, the Glee alum accused Grande of hitting on her fiancé.
“On the one day that he was back in LA, he said he didn’t want to see me. But since she had a key, she let herself into his house,” Rivera wrote, per Page Six. “I walk in, go downstairs, and guess what little girl is sitting cross-legged on the couch listening to music? … It rhymes with ‘Smariana Schmande.’”
Grande and the rapper were together for eight months before calling it quits on April 2015.
