If you aren't aware what a belfie is.... take a selfie of your butt and now your in the know. Apparently Nicki Minaj has been on a workout regimen, and that she’s working to lose weight and get in shape (for a possible summer tour?!). She wants the world to see so of course she had to post the Belfie on Instagram. She has a lot to be proud of, she shows off a super tiny waist and a big old butt while rocking spandex workout pants and a black sports bra.

Looks like the work out is paying off !
