Hugh Grant, Keira Knightley and Gwen Stefani are to appear on a charity version of 'American Idol'. The stars will join a host of other celebrities for 'American Idol Gives Back', a special edition of the talent show, which will help impoverished African children and Hurricane Katrina victims. Oscar winner Forest Whitaker, Teri Hatcher, Pink, Daniel Radcliffe and Helena Bonham Carter will also appear on the programme, which will feature some stars singing and others showcasing different talents.
A show insider said: "It's great that so many big stars have come forward to give their services for charity." The show's executive producer, Ken Warwick, is looking forward to seeing the high-profile celebrities perform on the show, but would not give too many details away. He said: "One thing I can guarantee is there will be humour and a few shocks. I know it will also move people to give generously."
