If you've ever wondered what P!nk looks like in her underwear, the new cover of Shape should answer all your questions.

In black Malia Mills bikini bottoms, a Hervé Léger bikini top and a Minimale Animale open-knit tank, the pop star is almost nude. Next to her, a cover line screams, "she dropped 55 lbs!"

Inside, P!nk shows more skin in a red Erin by Erin Featherston strapless dress, another bikini and in her workout gear: Stella McCartney for Adidas leggings, Asics sneakers and a Nike workout bra.

Regarding that 55 pound weight loss, the singer confesses that she employed celeb trainer Jeanette Jenkins and Biggest Loser coach Jillian Michaels to "kick her butt" and it sounds like her diet was pretty restrictive. The magazine details the process, which began with an "11-day power cleanse" and included a meal plan of quinoa, veggies, juices and smoothies.

Of course, P!nk's incredible physique isn't a surprise to anyone who's seen her the video for "Try" in which she performs many intense combat choreography while wearing little more than underwear and and a light dusting of chalk.
