Will and Jada Pinkett Smith are undeniably the most high-profile couple to publicly hint at an open marriage. And, following much speculation surrounding the nature of their relationship, Jada told Howard Stern in 2015 that husband of nearly 20 years Will has “all the freedom in the world.” She went on, “As long as Will can look himself in the mirror and be OK, I’m good.”

Dolly Parton and husband Carl Dean have long faced rumors that their 50-year marriage may be of the open variety. “I don’t want to know it, if he’s cheating on me,” the country legend admitted to the Daily Mail in 2007, adding, “If I’m cheating on him, he wouldn’t want to know it. And if we do, if that’s what’s making it work, then that’s fine too.”

Contrary to popular belief, it was Mo’Nique who instigated an open marriage with husband Sidney Hicks and not the other way around. “When I say I’m in an open marriage, it was not my husband’s idea,” the comedian clarified on Periscope in 2015, adding that she wanted to instigate a more open relationship rather than cheat on her husband of ten years.

Neil Gaiman has been more than happy to discuss his open relationship with wife of five years and former Dresden Dolls frontwoman Amanda Palmer. To that end, then, in 2013 the writer told The Guardian, “We would not allow another relationship to imperil what we have. We talk. And talk. And talk. And hug a lot. And talk some more.”

Basketball star Andrei Kirilenko has a rather unique arrangement with his wife Masha Lopatova. Yes, the former Brooklyn Nets player has been granted permission to sleep with another woman once a year. “What’s forbidden is always desirable,” pop star Lopatova explained to ESPN The Magazine back in 2006. However, at the time, Kirilenko claimed that he had no intention of actually using his annual hall pass.

And Kirilenko isn’t the only NBA star who appears to have been given the freedom to stray. According to an unnamed basketball player, Cleveland Cavaliers’ LeBron James – who married his high school sweetheart Savannah back in 2013 – is just one of many married men in the sport who are in open relationships.

Ethan Hawke has never been afraid to let his views on extra-marital affairs be known. The actor – who has been married to his children’s former nanny Ryan Shawhughes since 2008 – told magazine Mr Porter, “People have such a childish view of monogamy and fidelity.” He added in the 2013 interview, “[It’s] ‘He’s cheated so he’s bad, she’s cheated so she’s bad,’ as opposed to a recognition that our species is not monogamous.”

Alan Cumming has claimed that he and husband of nine years Grant Shaffer have a great sex life – but has nevertheless admitted that they may end up looking elsewhere in the future. “I don’t think it’s realistic to think that we are only going to have sex with each other for the rest of our lives,” the actor divulged to FourTwoNine magazine in 2014. “And I don’t think that’s the worst thing in the world.”

Few couples in the public eye have been more honest about their open marriage than Robert Crumb and fellow cartoonist wife of 38 years Aline, with both parties admitting to enjoying long-term affairs. Indeed, when asked about Aline’s other partner Christian Coudurès in a 2007 interview with The New York Times in 2007, Robert divulged, “Between Christian and I, we kind of make an ideal husband… but if she ever started making comparisons about our lovemaking technique, I might get jealous.”

It’s a little unclear whether Emma Thompson and husband Greg Wise – who got hitched back in 2003 – enjoy an open marriage. It seems, however, that the acclaimed actress certainly doesn’t appear to have any qualms about the concept, having once even branded monogamy as an “odd state” during a 2013 webchat with British parenting site Mumsnet.

Yep, the Senegalese-born star – who is married to Latrice Thiam but reportedly has six children by three different women – told TMZ in 2013, “Women aren’t built to mate with more than one party… men are.”

2. Brad Pitt and Angelina Jolie

They may be two of the most beautiful people in Hollywood, but that doesn’t mean that Brad Pitt and Angelina Jolie only have eyes for each other. “I doubt that fidelity is absolutely essential for a relationship,” Jolie – who married Pitt in 2014 – told German magazine Das Neue in 2009. “Neither Brad nor I have ever claimed that living together means to be chained together.”
