Kim Kardashian Shows off Incredible Figure, Promotes Waist Trainer

Kim Kardashian shows off her incredible figure on Instagram once again.

In the reality TV star's latest post, she is wearing her waist trainer while doing house chores. In the picture, the training belt, paired with an all black ensemble, makes her hourglass body look even curvier.

The picture is accompanied by a caption that reads, "Organizing & cleaning up before bed and waist training at the same time!"

Kim wore the same outfit earlier in the day when she was seen in West Hollywood. The star was reportedly filming a commercial for her very popular and successful app, Kim Kardashian: Hollywood.

Kim's younger sister, Khloe Kardashian also promoted the PreMadonna waist trainer earlier. In Khloe's post, her waist looks shockingly small with the trainer wrapped around it. With the picture, she wrote, "I am obsessed with my new waist shaper from @premadonna87!!! I mean how cute is this shaper?!?! Snatching my waist and looking cute all at the same time!!! I definitely feel like a superhero in this waist shapper!"

In other Kardashian news, Kim's childhood BFF Nikki Lund claimed that they were already dieting at the age of 13.

"At 13, we started to become more aware of ourselves. We began wearing make-up and started dieting," Lund said in an interview with Heat. "It was mostly the Atkins and the South Beach Diet. We did the Cabbage Soup Diet and we'd be there boiling great big vats of cabbage. We were like, 'Yes, we're going to be thin.'"

Kim has not commented about Lund's interview.
