She’s never been afraid of showing off her amazing physique, so it’s not exactly surprising that Zoe Saldana shed all of her clothes to pose for Women's Health UK magazine’s latest issue.

The 36-year-old “Avatar” actress, who is currently pregnant with her first child with husband Marco Perego, hinted in her interview that change is on the horizon.

Zoe shares, “My body is less toned. I do look in the mirror and see things I don't want. My first reaction is I breathe and I think, 'I'm a woman, I'm 36, my body is changing.’”

Furthermore, “This past year I've had to start letting go. My body dictated it as if saying, 'Slow the f*ck down!' ... And I struggle with that. I love to be an athlete.”

And while she tries her best to look flawless, Ms. Saldana is becoming less and less a perfectionist. “I'm exactly where I want to be. 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*ck it. Just be happy, regardless.’”
