Wow
Take note of the last item in IMDb's daily news round-up: http://www.imdb.com/news/wenn/2006-12-13/
Every person in that article is referred to by the proper title and style. Diana was always Diana, Princess of Wales, and never "Princess Diana," a style reserved for royal princesses. The styles "Prince William" and "Prince Harry" are acceptable shorthand (Prince William of Wales being the formal version), and "Sir Elton John" is quite correct, although the article could have referred to him later as "Sir Elton," had it wished to.
It'll never happen again...
