AMERICA'S GOT TALENT judge Piers Morgan has blasted Hollywood actress Keira Knightley for "moaning about being famous" - insisting she indulges in shameless self-promotion. The former newspaper editor is sick of celebrities who complain about unwanted attention from the paparazzi, but quite happily sign up for endless magazine photoshoots. And Morgan insists Knightley is one of the worst offenders. He tells British magazine Closer, "She moans about being famous and then does endless photo sessions. You can't use the media to promote yourself and then attack them! "My message to Keira is: 'If you'd like me to get off your case, stop bleating!' Most people would change their lives in a flash to have a tenth of what people like her have. Being famous is brilliant."
