Hollywood is notorious for it's celebrity divorces, so some couples have famously tried to combat that by agreeing to open marriages.
While most of these duos haven't outright admitted to engaging in this type of lifestyle, they've certainly alluded to it — like Angelina Jolie did in a 2011 interview.
“I doubt that fidelity is absolutely essential for a relationship," the mother-of-six told a German magazine three years before she tied the knot with Brad Pitt. "It’s worse to leave your partner and talk badly about him afterwards. Neither Brad nor I have ever claimed that living together means to be chained together. We make sure that we never restrict each other.”
Unfortunately for the duo, their nonchalant attitude didn't work out for them in the end, and Angie filed for divorce in September 2016.
One couple it has worked for is Mo’Nique and her husband of ten years, Sidney Hicks. The Precious actress told Barbara Walters that she could have sex with another man if she wanted to, but hasn't. Though that may have changed in the past few years!
