10 Celeb Open Relationships

How do celebrity couples keep things exciting in their relationships? Well, some of them do so by keeping things ... open. The Frisky rounds up 10 famous couples who are said to be in open relationships—and some have even admitted it:

• No rumors here: Mo'Nique has said herself that her marriage to Sidney Hicks is open. "Could Sid have sex outside of his marriage with me? Yes. That's not a dealbreaker. That's not something that would make us say, 'Pack your things and let's end the marriage.' What if it's 20 times? So what? We've been best friends for over 25 years, and we truly know who we are."
• Brad Pitt apparently got a little upset when Angelina Jolie said, "I doubt that fidelity is absolutely essential for a relationship. It’s worse to leave your partner and talk badly about him afterward. Neither Brad nor I have ever claimed that living together means to be chained together. We make sure that we never restrict each other."

• Of his marriage to Jada Pinkett Smith, Will Smith once said, "Our perspective is, you don’t avoid what’s natural and you’re going to be attracted to people. If it came down to it, then one would say to the other: 'Look, I need to have sex with somebody. Now I’m not going to do it if you don’t approve of it.'"
• But not all relationships are even: Supposedly, Megan Fox is allowed to see other guys, but hubby Brian Austin Green doesn't have similar freedoms.
