Cindy Crawford once turned down a date with Prince William, because he was just a teenager at the time.

The supermodel was flattered when William's mother, DIANA, Princess Of Wales, asked her to meet her son, who was a huge fan - but she was aware the young royal was underage.

She tells Maxim magazine, "I thought, 'I could be your mother!'

"His mother called me once when I was in London to come meet him, but he was only 16 (sic) at the time. He has turned into quite a nice-looking young man."
