Kardashians Teaming up for a sexy new ad campaign.

Teaming up for a sexy new ad campaign, Kim, Kourtney and Khloe Kardashian used their good looks in hopes of selling a little more product.

The E! reality sisters tossed on a little lingerie as they posed for world-renowned photographer Annie Leibovitz for a Kardashian Kollection Sears promotional effort

The photoshoot took place back in May, with Kim writing about the experience on her blog by telling, "What an amazing day! We shot with the living legend herself, Annie Leibovitz! I swear this was such an eye opening day. She shot our Kardashian Kollection for Sears ad campaign!"

The newlywed brunette beauty added, "I can’t give away any details, but we have never been shot like this before and it was soooo fun shooting with Kourtney and Khloe… Mason even made a cameo!"

Meanwhile, Miss Leibovitz was seemingly so taken by the Kardashian sisters that she's hosting a party for the ladies at her New York City studio next week.
