This bad girl with a good girl's face loves to take sexy pictures of herself, even though they always seem to find their way online. In September 2007, the 18-year-old "High School Musical" star's computer was hacked, and her private pics surfaced. Then, two years later, another set of naked photos of the ingénue went viral -- and this time, she sued. But Vanessa still didn't learn her lesson, and in March 2011, a third batch of sexy shots hit the Web. And to think, Gabriella and Troy didn't even kiss until "High School Musical 2."
