Cameron Diaz Shares Her Beauty Secret

Perhaps we all have the same question, how does Cameron Diaz maintain those mile-long legs and billion-dollar grin?

According to her is Sex, and lots of it!

The 37-year-old actress reveals one of her beauty secrets to British Vogue in its July issue, "I don't want to look 25 again," but she acknowledges that she looks pretty good.

"The fountain of youth, 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!"

She also mentioned that she has not yet relied on plastic surgery to keep her good looks.
