Pink - Pink Quit Smoking To Breastfeed

The So What hitmaker gave up her wild child ways when she became a first-time mum to daughter Willow Sage a year ago (Jun11) - and she made a pledge to get healthy so she could nurse her newborn, even if it cramped her recording style.

She tells Cosmopolitan, "I'm used to going into the studio and smoking and drinking until three in the morning. But I can't drink as much because I'm breastfeeding. See this glass of wine? Before, I'd have, like, four of them. Now, one is good. Oh, and I quit smoking..."

But Pink insists she knows she has a long way to go before she can call herself a perfect mum: "I've exorcised a lot of my demons but I'm still working on myself. I think I'll be a work in progress for the rest of my life."
