"I'd quite like to go on 'Dancing with the Stars,'" Ferguson tells "Inside Edition" in an interview 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.
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.
