Check your calendars! If Kim Kardashian isn't on it yet, she will be!

The reality star, 29, has revealed behind-the-scenes photos from one of her two upcoming calendars. Kardashian is doing two 2011 calendars, "one with my blonde hair and one with brunette hair," she writes on her official blog.

"We did the blonde shoot last year right before I went back to my darker look and decided I wanted to capture the blonde look, so what better way to do that than to create a calendar?" she says.

As for the dark-haired version, photographer Nick Saglimbeni snapped her in skin-tight bathing suits showcasing her famous curves and trademark booty.
