Miley Cyrus has been announced the worst celebrity influence of 2010, for the second time in a row now.The 18-year-old took in a whopping 58 percent of the 99,000 votes in the poll for AOL''s JSYK.com (Just So You Know) website, which has a target audience of 9-15 year olds.While last year she beat Kanye West and Britney Spears, this time she has toppled Lindsay Lohan volatile "Teen Mom" Amber Portwood and punch-happy Disney star Demi Lovato.First she was caught on video smoking Salvia from a bong in December, and then photographed lifting her shirt almost to her chest in a series of scandalous photos taken at a gay club, reports the New York Daily News.In May, she was criticized after a video showed the then 16-year-old "dirty dancing" at a wrap party for "The Last Song" with Adam Shankman, the film''s much-older producer.Her outfits caused quite a stir too - with the singer choosing to wear lingerie-like outfits during a number of concerts and writhing around in a bed while barely dressed for her "Who Owns My Heart?" music video, drawing the ire of the Parents Television Council.
