At 37, Cameron Diaz still looks fabulous as ever. Here’s her secret: “Lots of sex,” apart from the usual beauty tips.

The Hollywood actress shared with British Vogue recently about what makes her young:

“The fountain of youth (for me), let’s see...I guess it’s exercise, healthy diet, lots of water, lots of laughter, lots of sex - yes, sex, we need that as human beings. It’s healthy, it’s natural, it’s what we are here to do!”

Even though it seemed that it might be the last thing she needs, Diaz is not dismissing the possibility of going under the knife in the future.

“Yeah, well, hey. I’m not doing anything right now, but we’ll see. So far, so good. But I’ll never say never to anything,” she said.

However, the Hollywood actress is not so open when it comes to her rumoured relationship with baseball star Alex Rodriguez.

“You know what? Yes I am. I'm in love with life,” she said coyly when quizzed about the romance.
