Socialite sisters Kim and Khloe Kardashian slap their stamp of approval on Quick Trim for a new commercial advertisement promoting the weight loss system.

“SEXY! U can see our QuickTrim commercial on QTdiet.com FIRST before it airs on TV!” Kim Tweeted just an hour ago.

Kim and Khloe are showing off their svelte new figures in the super-sexy new spot. Kim, 29, and Khloe, 25, appear on screen wearing buttoned-down white collared shirts before ending up poolside in bikinis.

“You can change the way you look…create the body you deserve,” a tantilizing Kim tells the audience.
