FILE -- In this Dec. 11, 1995 file photo, Diana, Princess of Wales, smiles at the United Cerebral Palsy's annual dinner at the New York Hilton. Princess Diana would have been 50 years old on Friday, July 1, 2011, perhaps the only certainty about the course of a life abruptly cut short in a 1997 car crash in Paris, with a new boyfriend, two months past her 36th birthday.
