Khloe Kardashian Joins The 'Waist Gang'

Khloe Kardashian wants you to see her waist.

The reality star posted a selfie Friday, May 2, showing her dressed in a tight black shirt and skinny jeans. The main focus, according to her caption, was her waist.

"I love my waist trainer from @premadonna87!!!! Miss @blacchyna has me obsessed!!! Who doesn't love to feel tight and right?!? 😍 #whatsawaist #waistgang #Fitness #GetItRight," she wrote.

Premadonna is the CEO of the Waist Gang Society, selling reshaping garments for waist training. Apparently, the Kardashians' friend, Blac Chyna, is also a fan. The Miami native and aspiring rapper thanked Kardashian for the mention. "ALL YO MAMA EVER MADE WAS TROPHIES RIGHT????????" she added, referencing Kanye West's lyrics about the Kardashian beauties on Future's "I Won."
