Today marks the 30th anniversary of the VMAs, and we're very excited about it here at POPSUGAR. We've all been talking about some of the most memorable moments, from Britney and Madonna's kiss to Paul McCartney mispronouncing Lauryn Hill's name. But there's really nothing we love more than our favorite celebrity falling out of the sky. Beyoncé, Jessica Simpson, and Pink have all done it. Today we're looking at our favorite high-flying VMA performances.
