The 33-year-old wrote, "#tbt calendar glam" on the sexy pic.
Kim is shown checking her cellphone while she sits in a makeup chair and gets the finishing touches of her bronzer carefully applied.
The striking brunette appears to be wearing nothing but thigh-high boots and a leather jacket during the sexy photo shoot—showing off her ample curves and bust line in all its glory.
Kim's been flaunting her post-baby bod for a while now, and speaking out against haters that claim she went under the knife to drop the weight, but it's clear from this pic that she's been sexy from the start!
But this wasn't the only throwback pic to surface this week…
A photo from New York Fashion Week in 2009 showing Kim sitting just one seat away from Kanye West also made its way onto the Internet!
The E! reality star sat next to her then-boyfriend, Reggie Bush, during the Y-3 show, while the famous rapper attended with pal Lupe Fiasco.
Kim looked as chic as ever in leather leggings, YSL pumps and a white-and-black blazer while West ditched his leather jogging trousers for a pair of preppy khakis.
My oh my how the times have changed!
