NEW YORK  —  Actors and athletes have busted some amazing moves on "Dancing with the Stars," including its new champion, football great Emmitt Smith. Sarah Ferguson, the Duchess of York, is hoping the show will make room for a royal.

"I'd quite like to go on `Dancing with the Stars,'" Ferguson tells "Inside Edition" in an interview that was scheduled to air Thursday. "I'd like them to teach me the tango."

Ferguson, 47, says she was turned on to the romantic dance during a visit to Buenos Aires, Argentina. "I did go to the oldest tango place and I did look at it and think `I can try this,'" she said.

The muscular Smith, a three-time Super Bowl champion and all-time NFL rushing leader, out-hoofed actor Mario Lopez to win the third edition of the hit ABC show.

Ferguson and Britain's Prince Andrew — aka the Duke of York — divorced in 1996. They have two daughters, princesses Beatrice, 18, and Eugenie, 16.

Ferguson also published a best-selling memoir, "My Story," in 1996 and went on to become a spokeswoman for Weight Watchers.
