Earlier this month, Kim Kardashian posted a photo to Instagram of her posing topless in front of a mirror with a black bar Photoshopped across her ample breasts. Guess what -- she's at again, and this time she's joined by super model Emily Ratajkowski. The two of them stand casually topless in front of a bathroom mirror.

Ratajkowski is perhaps best known for her topless role in Pharrell and Robin Thicke's "Blurred Lines" video, her spreads in the Sports Illustrated Swimsuit Editions, and for "Odelling" the wedding bouquet in a Super Bowl commercial earlier this year.

That's two semi-nudes from Kim one month... don't be surprised to see her kick things up a notch in April.
