Rule No. 1 for red carpets: Always look in the mirror before you step out onto the carpet. Apparently, after decades of being in Hollywood, Nicole Kidman forgot that imperative. Otherwise, she would have never showed up at the New York premiere of "Nine" looking like this. OK, so Nicole's not the only celeb to suffer this powder faux pas: Drew Barrymore, Eva Longoria, Uma Thurman and Ashley Judd have all suffered the same fate, which has been attributed to camera flashes bouncing off their Make Up Forever HD powder.
