Look at that waist!

Nicki Minaj posted a series of sexy photos via Instagram on Monday from a mystery shoot. We're not sure if this is for a new music video or a fashion pictorial, but either way, she look great.

And Minaj was decked out in some awesome designer wear as well.

Sporting a black netted one-piece suit, a gold chain embellished jacket, lots of bling and sexy black boots, the "Starships" singer was rocking it while rocking a super cinched-in waist.

"Jacket by @moschino belt by @balmainparis boot by @louboutinworld Gold Medallion by @versace_official and Haas Brothers - bracelet by @celinebags rings by @robertocavalli and La Ruicci BodySuit by Luxe & Le'Bra - additional jewelry by M&J Savitt," she tweeted with the sultry snap. 

The 31-year-old also debuted her natural hair last week -- posting a photo of her holding her long brown locks in the air. 

"No perm. No extensions," she captioned with the candid photo. We gotta say, we're loving Nicki's natural 'do!
