Sarah, Duchess of York
[Sarah] Ferguson's relations with the royal family, which have always been up-and-down, took a major nose dive just as things were looking up for the duchess. The famously spendthrift Ferguson has worked hard to balance her checkbook and has devoted herself to various charities and business ventures....Although Ferguson divorced Andrew in 1996, the two have maintained an affectionate friendship and even live under the same roof in a royal residence in Windsor. In 2008, the queen invited her to the royal family's annual sojourn at Balmoral Castle. The duchess is fond of saying that she and the duke are "the happiest divorced couple in the world."... After her marriage to Andrew in 1986, Ferguson was initially considered a breath of fresh air for the royal family. But it wasn't long before Britain's fickle tabloids soured on the lively, rambunctious duchess, who was accused of going on too many vacations, accepting too many freebies, eating and drinking too much, and generally flouting royal protocol.
