It's sometimes the natural order of things for women to put on some weight during pregnancy. Pop stars are not excluded. Pink, for example, added more than a few pounds to her frame when she was pregnant with her daughter Willow Sage Hart.

“I ate a lot of cheesecake during those nine months," she says. "Also anything sour, Sour Skittles, Sour Patch Kids, Key Lime Pie."

But more than a year after giving birth, it seems the 33-year-old has her physique back. She appears on the cover of the November issue of Shape sporting a body that is 55 pounds lighter than it was back when she was pregnant.

That's pretty impressive.
