Pink Loses 55 Pounds, Debuts Weight Loss On SHAPE Magazine Cover (PHOTO/VIDEO)

P!nk has dropped a whopping 55 pounds since she had her baby and debuted her new, toned body on the cover of SHAPE magazine.

The singer flaunted her svelte figure on the November issue of the fitness magazine, wearing little more than black underwear and a sheer top with her signature pompadour haircut.

The "Raise Your Glass" singer flashed a winning smile as she raised her shirt to show off her well-defined stomach.

The 33-year-old has impressed critics in several reports because she has achieved getting her post baby body back just a year after delivering her first child, daughter Willow.

In an excerpt from the magazine's cover story, the singer admitted she wasn't eating very healthy; a "sweet tooth" helped her put on the excessive weight.

"I ate a lot of cheesecake during those nine months," Pink reportedly told SHAPE. "Also anything sour, Sour Skittles, Sour Patch Kids, Key Lime Pie."

Pink also confessed to her previous "wild child" ways - she started smoking at just nine-years-old and overdosed in a nightclub at the age of 15.

"I was 9 [when I started smoking]. By the time I turned 12 I was smoking a pack a day. I quit when I got pregnant. Unlike before [Willow was born], cigarettes smell repulsive to me."

As for the drugs, she took as a teen: "I was into ecstasy, Special K, crystal meth, acid - you name it."

P!nk also flaunted her new physique in her latest music video for the song "Try." According to one of her tweets, Pink's mother was "speechless" and "uncomfortable" after seeing it for the first time.

"My mom, after seeing the new video... 'Wow, honey. I'm speechless. And uncomfortable. No one can ever say you play it safe.' Thanks, mama," Pink tweeted.

P!nk wore lingerie as she danced throughout the video with a topless hunk, dancer Colt Prattes. In the video, the two are seen kicking, throwing and choking each other ... something Pink's mom was apparently shocked by. 

The video was directed by Floria Sigismondi and the sexy fighting dance moves were choreographed by The Golden Boyz.
