Cameron Diaz Cheating: 'The Other Woman' Star Sparks Debate! 'Everyone Will Be Cheated On!' Aerosmith’s Steven Tyler Disagrees!

Cameron Diaz is a carefree spirit. Even without watching the infamous car scene in "The Counselor" it is easy to conclude on that. The star of "The Other Woman" explores her movie's theme: Infidelity.

In a conversation with OK Magazine, Diaz drags us all down with her:

"Everybody has been cheated on. Everyone will be cheated on."

She says it's a fact that we have to accept. "I can't fix that. I don't know how. I don't have any judgment on anybody. I don't know how to fix the problem."

In her film "The Other Woman" Diaz's character finds out that her boyfriend has a wife - and another girlfriend. She thinks it is not a work of fiction.

"My statement is that I am actually not interested in making movies about men cheating on women; it's not at all what I'm interested in. We are human beings, we are complicated." (That explains the Facebook relationship status).

Her advice: "You cannot go through life without tallying up a few scars, you cannot go through life unscathed, it's just what it is. It's all meant to happen, take your lessons, figure it out, move on."

She's not alone in that view. Scarlett Johansson, who's now pregnant and engaged to Romain Dauriac  shares a similar view. In 2008, she told W magazine: "I've been battered for saying that I don't believe humans are monogamous by nature." Good luck with that, Mr. Dauriac.

Ethan Hawke, who was divorced by Uma Thurman amid infidelity accusations, shared (from Yahoo): "People have such a childish view of monogamy and fidelity. '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. To act all indignant, that your world has been rocked because your lover wasn't faithful to you, is a little bit like acting rocked that your hair went gray."

But the claim that it's a human nature thing, and that it's inevitable is disputed by some happily married celebrities.

Claire Danes of "Homeland" has been married for four years now. Speaking to Blackbook: "We just can't shake monogamy. It definitely demands a kind of rigor and discipline and selflessness. But it's also fun."

And the most surprising defender of monogamy, Aerosmith's frontman and former "American Idol" judge Steven Tyler! He said on Oprah: "I may come off as a sexual animal, and I definitely am on stage, 'cause trust me, I feel it myself. But I'm not really, really that. I'll sing about it, I put it out there, but I'm not."

Is monogamy an unrealistic goal or a prerequisite for a relationship? What do you think?
