On 31 August 1997, Rees-Jones was seriously injured in the crash that resulted in the death of Diana, Princess of Wales. The Princess' boyfriend, Dodi Fayed, and the driver of the car, Henri Paul, were pronounced dead at the scene; Rees-Jones was the only survivor. His face was flattened, with numerous bones broken or crushed. His face was reconstructed from family photographs by maxillofacial surgeon Luc Chikhani, using about 150 pieces of titanium to hold the bones together and recreate the original shape. Within a year, his face was nearly back to normal.
