Daniel Radcliffe is stepping in front of the camera for a good cause - he's lending his image to Sir Elton John for a book to benefit the singer's Aids Foundation. The Harry Potter star will pose alongside fellow actors Clint Eastwood, Robert De Niro and Al Pacino in the coffee table book, iCon, due out later this year (11). The book will feature a total of 100 stars and a portion of the proceeds will go to the Rocket Man's charity.
