Kim Kardashian offered a sneak preview of her sexy 2011 calendar via her Twitter account on Thursday. The photo features an oil-covered, bikini-clad Kim Kardashian lying on her back and resting on her famous posterior.

Kim Kardashian tweeted:

“New twitter background. It’s a sneak peak from an upcoming calendar shoot. It will be up only for one night!”

The shot definitely shows off her main assets. The picture is titled “June,” and will presumably be the image for that month in 2011.
