"I have hips!" the actress, 45, and Fitness bikini cover girl says in the magazine's May issue. "I'm never going to be the thinnest actress, and I don't want to be. When you're at peace with yourself and your body, you're automatically more confident."
But that doesn't mean the Sex and the City 2 star doesn't work hard to get toned and fit. Once an avid runner (she used to do seven miles on a beach before suffering ankle injuries), Davis now turns to the elliptical, yoga, Pilates and even some jumping jacks with resistance bands when she's on the road traveling.
And when it comes to food, the actress has a few rules she lives by: Keep it healthy (chicken and salmon and side salads) but also indulge once in a while.
"If all I ate were salads ever day, I'd shoot myself," she says. "Who cares if you can fit in your skinny jeans if you can't enjoy life and have something good to eat?"
For Davis, that includes chocolate – "I especially love M&M's," she says – and ice cream.
"I went through periods when I said I can't have this, I can't have that," she recalls. "Now I don't deprive myself. Food is meant to be enjoyed."
