As one of the most famous women in the world and a style icon, we imagine these waist trainers will be sold out in no time and it's not the first time she's admitted she's obsessed with them.

It definitely seems as though the waist trainer is working because her husband, Bound 2 rapper Kanye, just can't get enough of her fabulous body.
