Cameron Diaz is known for a couple of things: the "hair gel" scene in There's Something About Mary, and the fact her body gets more fit with age.
Cammy turns 40 this month, and in order to help spread the fountain of youth to all her fans, Harper Collins has commissioned her to write a health, wellness and fitness book, sharing all of her everlasting secrets.
We can bet there will be a lot of lunge and squat exercises in the manual, as Cameron has touted the effects of exercise on her famous derriere.
"My a** is definitely higher than it was when I was 20," she told Access Hollywood in May. "This is the thing that people don't understand — take care of your body [and it wil] get better! It gets better as I get older."
Rather than fixate on the fact she's entering her 40s, the Bad Teacher star has a rather enlightened view on age.

"Look, the alternative to getting older is dead, so… I feel very fortunate to have a very full, loving, blessed life, so I'm living it to the fullest," she said.
The book is slated to hit shelves in the fall of 2013.
