Pink posed in her birthday suit for the cover of Who magazine's upcoming body issue, showing off her curves and tattoos.


Pink is one of 14 stars who stripped down for the mag, and talked about confidence and body image.


She said, "I'm in the best shape of my life," and says her confidence stems from knowing she’s fit even though she’s "ten pounds heavier" than she was before her pregnancy.


Pink hopes to pass that mindset along to her 3-year-old daughter, adding that her daughter asked to have a "naked booby butt dance party” and she replied, 'I'm in!’"
