Listen to Nicki Minaj on iHeartRadio

Perhaps there’s a reason that Nicki Minaj shares all of these body-baring photos with the world.

In this latest one, she reveals that she’s been on quite the workout regimen, and that she’s working to lose weight and get in shape (for a possible summer tour?!). In this latest one, she shows off a super tiny waist and a big old butt while rocking spandex workout pants and a black sports bra.

“5 more lbs to go,” she captioned the photo.

She also shared another close-up shot of her hindquarters with this caption: “Cuz it’s finally famous,” which is in reference to her rap in her verse of Big Sean‘s “Dance (A$$).”

So what’s her workout regimen? Running with her longtime bestie! She tweeted this before she went out on said run: “F-k. I was laughin n f–ked up the caption. I said: went runnin wit this psycho. Friends since 14. I never quite got her screen name. @spoonfulofsass lmfaooooooooo like wtf is a spoon full of sass Thembi?!??!?!!”
