Sarah Ferguson opened up to Oprah about the reasons she betrayed the royal family when she offered a News of the World reporter access to her ex-husband Prince Andrew in exchange for money. She and the Duke of York had divorced in 1996, and she was estranged from the royal family. In that time she accumulated debt and had "been in the gutter at the moment." Winfrey also got her to admit to drinking and having an eating disorder, and to watch the video footage that caught Fergie in the act after she admitted that she had never watched it in its entirety.
Fergie made another appearance on Oprah's show, pictured here, to promote her reality series "Finding Sarah," which will air on OWN. She also spoke out about her snub from Prince William and Kate Middleton's royal wedding and announced that her daughter Princess Beatrice would auction her memorable wedding hat for charity.
