The period before one of her films is released should be an exciting time for Vanessa Hudgens, and yet the same story has played out in the run-up to each of her last few projects: A hacker spoils her promotional tour by leaking ever-more-graphic private photos of the actress. After the last batch hit the web this past week, Hudgens finally got the FBI involved, and TMZ reports that investigators are closing in on a hacker who compromised the private e-mail accounts of almost 50 celebrities, including Scarlett Johansson, Miley Cyrus, Ali Larter, Busy Phillips, and, er, Buffy the Vampire Slayer co-star Emma Caulfield. (Dude, don’t cross a vengeance demon.) [TMZ]
