INTERVIEW: Cameron Diaz gives a very interesting take on monogamy

We sat down with the stars of the new comedy to get their takes on monogamy and find out if the old adage, “Once a cheater, always a cheater,” is true.

We started with the men and asked Taylor Kinney and Nikolaj Coster-Waldau if they think humans are capable of monogamy. Both gentlemen said yes, but the super-sexy Coster-Waldau was quick to qualify his answer.

“I think we’re all different. It works for some and not for others, but I think you should have one partner at a time. Whether that’s one year or five years or 20 years, that’s life.”

Cameron Diaz plays Carly in the movie and Carly says, “Once a cheater always a cheater.” We asked if Kinney and Coster-Waldau agreed.

“I want to believe in change and it depends on who you’re with. I think there are people in relationships where it’s not really love. I want to believe that if you’ve found true love and really dedicated yourself, I’d like to think you won’t cheat,” said the Game of Thrones star.

Kinney added, “I don’t like the idea of living your life by a quote. If you’re going to be with a person then be with them. If you’re not going to be true to them, then kick off.”

We also asked which is worse: physical or emotional cheating? “Clearly physical. If my wife looks at a guy and gets an idea, that’s absolutely OK, because I’m not going to go into her mind. But if it were to go further than that, I wouldn’t be OK. I don’t think you can control your mind all the time.” Good to know, Coster-Waldau.

We also sat down with the leading ladies of the film and asked why people cheat on their spouses.

Leslie Mann said, “People grow and change and if you meet someone when you’re young, 10 years later you’re a different person and maybe they’re not, that’s hard. But hopefully you can grow together.” Clearly, that’s what she and movie-director husband Judd Apatow (This is 40) are doing.

Cameron Diaz added, “Monogamy doesn’t mean you have to spend the rest of your life with somebody. It just means that when you’re in a relationship, they’re the only person you’re having sex with.”

So, what should a gal do if she finds out her spouse is cheating?

“I think you can’t change someone. If that’s who they are, you need to either be OK with it or get out. I really believe you can’t make people different than they are. They can change themselves. They don’t always have to repeat the same patterns,” said Diaz.

“Men generally tell you who they are day one, if you listen. But women don’t want to hear it. Sometimes it’s like a red flag,” said Mann.

Kate Upton added her advice, too.

“I thinks it’s best to just move on and don’t stay in something that’s emotionally damaging. It’s not your responsibility to be there every step of the way. Even if they want to change you have to step away.”
