Georgia Arianna, Lady Colin Campbell (née Ziadie, born 17 August 1949), also known as Lady C, is a British Jamaican author, socialite, and television personality who has published seven unauthorised books about the British royal family. They include biographies of Diana, Princess of Wales (which was on The New York Times Best Seller list in 1992), of Queen Elizabeth The Queen Mother, and of Meghan, Duchess of Sussex and Prince Harry, Duke of Sussex.
Born into the Ziadie family, a prominent family of Lebanese descent, she grew up in the Colony of Jamaica as the child of a wealthy department store owner. Campbell was born with a genital malformation and, following the medical advice of that time, was raised as a boy despite being female. She moved to New York City to attend the Fashion Institute of Technology and began working as a model. In 1970 she had corrective surgery for her congenital vaginal malformation, funded by her grandmother. She legally changed her name from George William Ziadie to Georgia Arianna Ziadie, receiving a new birth certificate. While in the United States, she met and married Lord Colin Ivar Campbell, the second son of Ian Campbell, 11th Duke of Argyll and Louise Hollingsworth Morris Clews. The marriage quickly soured and they divorced nine months later following a scandal surrounding her physical characteristics at birth.
As well as being a royal biographer and a royal commentator, Campbell is a reality star who has made appearances on Comedy Nation, I'm a Celebrity...Get Me Out of Here!, Celebs Go Dating, Salvage Hunters, Through the Keyhole, Good Morning Britain, and Celebs on the Farm. She admits to liking the recognition.
She is the châtelaine of Castle Goring in Worthing, the ancestral seat of the Shelley baronets. She ventured into reality television to cover the castle's renovation costs, which she called "whoring for Goring". She purchased the mansion in 2013.
