If you tune into the Kentucky Derby Saturday don't be surprised to see some royalty. The Sport of Kings will host England's Queen Elizabeth II.

"It says something about the Derby that it has universal appeal from the royals to us regular folks," Louisville Mayor Jerry Abramson said. "Louisville shines on Derby Day."

The Queen is said to be a big fan of the Sport. She must of heard good things about the event as Princess Margaret, sister of the queen, attended the 1974 Derby with her husband, Lord Snowdon.
