Maybe her ass really does look like “cottage cheese in a big trash bag.” Kim Kardashian has proudly confessed that her bodacious backside is far from perfect. The brunette has confirmed whispers that surfaced earlier this week, claiming that the E! reality star has been undergoing treatment for an embarrassing battle with cellulite-that’s why on Sunday’s episode of Keeping Up with the Kardashians Kim takes us along as she tries the VelaShape cellulite reducer in a bid to smooth out her dimply derriere.

The VelaShape machine uses a combination of infrared light, radio frequencies and massage to exfoilate cellulite from skin cells.

“I work out all the time but I have a little cellulite,” Kim says. “It’s this big huge machine that basically gives you a massage,” she explains. “It tickles but it’s hot at the same time!”

Kim takes on the cellulite on Keeping Up with the Kardashians, airing this Sunday, May 11th at 10 pm on E!
