Reality TV and music star Ashlee Simpson has reason to sing the blues. First, she was caught lip-synching on Saturday Night Live, then she was booed after a performance at the Orange Bowl, and now Jessica Simpson's little sis is the target of an online petition. More that 17,000 people have added their digital signature to the petition, which asks Ashlee to "stop recording, touring, modeling and performing." The petition was created by 18-year-old New Yorker Bethany Decker.
