Breakout poptress Ke$ha is up for three MTV Video Music Awards and is slated to present an award when the festivities kick off Sunday, September 12, at 9 p.m. The "Tik Tok" singer is sure to fit right in amid the typical VMA rowdiness, and even the promo for her appearance is chock-full of high-flying stunts and other craziness."The concept ... is I wake up, like a pimp, and I hear some noise, and there's like a wind coming through my boudoir doors, and I run to see what it is, and I just get shoved out by this gust of wind that's supposedly 'fate,' " Ke$ha said, setting up the clip. "Then, I start falling and falling through ... all of my experiences that got me to this point, which is attending the VMAs."Creating the illusion of a free fall for the spot required Ke$ha to swing about on a harness, an experience that apparently looks way more fun than it feels."I did do all my own stunts today, and my vag hurts," Ke$ha griped. "It was kind of scary, because ... I was flying around." Being suspended may have been a bit harsh on her lady bits, but the singer said she's no novice when it comes to hanging around for her videos. "I have used some harnesses before [on] my video for 'Blah Blah Blah.' ... I'm into it."Ke$ha may have some experience getting strapped into harnesses, but she also admitted that dangling from the contraption was the hardest part of filming. "I think the harness was scarier, only because it was immensely painful as well, and I couldn't touch the ground," she said. "I thought I was gonna fall on my head, but I didn't."Ultimately, the "Your Love Is My Drug" singer wasn't sweating any of the potential risks of shooting the promo."I was only, like, 12 feet high," Ke$ha said. "Worst-case scenario: I just would have, like, broke an arm."What are you expecting from Ke$ha's appearance at the VMAs?
