R+B superstar Beyonce Knowles refuses to blame her clothes for on-stage mishaps - and points the finger at her own clumsiness instead. The Deja Vu hitmaker, 26, famously tumbled down a set of stairs during a U.S. concert in July (07) - but admits accidents happen to her so frequently she can't hold her fashion choices responsible. She says, "I recently fell down the stairs because my heel got caught in the hem of my coat. "But really, I've fallen down the stairs a lot of times, so I can't only blame it on the coat."
