Pink gave birth to daughter Willow last year, and already, the 33-year-old rock star's body is bangin'!

The "Blow Me One Last Kiss" songstress is showing off her 55 lb weight loss on the cover of Shape magazine.

Pink, who now stays faithful to a regular workout plan, tells the mag:

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


The singer also admits to starting her smoking habit at age 9. She has since quit, but talks openly about her past drug use. Pink adds: "I was into ecstasy, Special K, crystal meth, acid - you name it.”

Great voice, great body ... and now a great role model!
