Zoë Saldaña isn’t afraid to grin and bare it…

Saldaña bared it all for the magazine, with only a rib cage tattoo covering up her skin.

The Guardians of the Galaxy star tells Women’s Health: “This past year I’ve had to start letting go. My body dictated it as if saying, ‘Slow the f— down!'”

As a result, Saldaña says her body is “less toned. I do look in the mirror and see things I don’t want.” But in some ways, she’s never felt better about her appearance.

“I do feel beautiful in a way that even when I was working out a whole lot, I sometimes didn’t,” Saldaña tells the magazine. “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— it. Just be happy, regardless.”
