Kim Kardashian [1] proved that, yes, she can really balance a Champagne glass on her butt like she did for her now-infamous Paper magazine photo shoot [2], and she's willing to share her secrets with the world. The reality star made an appearance on Australia's The Project on Tuesday to open up about her Internet-breaking stunt with photographer Jean-Paul Goude. After host Rove McManus asked Kim if the Champagne butt shot was photoshop, she clarified that it was indeed real and that her "back hurt for a week after the shoot" due to the intense pose. "It was definitely not comfortable, and things were falling all over the place," she added. Kim then agreed to show Rove, although she added that it might not work because he doesn't have "as big of a butt as I do." Watch the hilarious balancing act above and hear more from Kim about why she did the shoot.
