Cameron Diaz talks botox, children and marriage

Cameron Diaz is not a California girl - she is

In an exclusive interview with Elle magazine Cameron Diaz opens up about working with her ex boyfriend, Justin Timberlake, on her new film, Bad Teacher, and living out of a suitcase whilst dating US baseball star, Alex Rodriguez.

At age 38, Diaz says she has never had botox and her strict diet and exercise regime is what maintains her enviable physique.

The Hollywood A-lister also stated that marriage isn't always the best idea.

Cameron said: "I think a lot of people are married to people that they're not romantic with any more.

"I just didn't ever marry anybody that I then had to get divorced from. We break up. We move on. All I want for him is happiness. All he wants is my happiness. His isn't reliant on me, and mine isn't on him."

On her outlook on life now she is approaching 40, Diaz comments: "I used to be a very, very, very cynical person. I'm not a tortured person. I have been in my past but I don't like to project that. But I'm a realist. I see things how they are and it's hard to pretend that they're anything different."

The full interview appears in the June issue of Elle Magazine, on sale now.
