Zoe Saldana has learned to embrace her body flaws after deciding to relax her work-out and diet regime in the past year.

The pregnant Avatar star has bared all for the September (14) cover of Britain's fitness and lifestyle magazine Women's Health, but explains she doesn't look her best because she hasn't been exercising as much as she used to.

The 36-year-old mum-to-be, who posed for the photoshoot weeks before going public with her baby news, says, "This past year I've had to start letting go. My body dictated it as if saying, 'Slow the f**k down!'

"I'm less toned. I do look in the mirror and see things I don't want... (but) I do feel beautiful in a way that even when I was working out a whole lot, I sometimes didn't, because there have been times that I was really slender and I didn't like that I sometimes looked a little too muscular and flat-chested. You'll never be completely happy, so, at the end of the day, it's like, 'F**k it! Just be happy, regardless."

In her revealing new cover shoot, a seated Saldana poses with her knees tucked into her chest to cover up.
