The honor is somewhat bittersweet for the mom-of-three given she's the first to have the honor since Princess Diana's death, and her newfound status seems to have dredged up the Middleton family's questionable past.
"Before William set the date for their much-anticipated wedding he had to face some of Kate’s unfortunate connections that a future British Queen would really rather keep hidden," spilled a source, pointing fingers to her troublesome uncle, Gary Goldsmith.
The 44-year-old, who is the brother of Kate's mom, Carole, was caught offering drugs to a reporter, in addition to boasting ties to a prostitution ring. "William adores Kate’s parents, Michael and Carole, but he had no choice but to cut all ties with her uncle," the source noted. "Everyone felt bad for Kate — because it’s not like you can choose your relatives."
Goldsmith was also arrested plead guilty to beating his wife, Julie-Ann.
The Duchess of Cambridge's brother, James, has caught heat as well, as he was once involved with the company Forestry For Life, which turned out to be a get-rich-quick scheme, and after less than two years, the authorities seized its assets.
In addition, it was revealed that Kate's old pal Emma Sayle ran Killing Kittens, a company that puts together swinger parties.
Regardless of the resurfaced scandals, Kate, 40, is determined to do her new title justice, with one source sharing, "The new Princess of Wales appreciates the history associated with this role but will understandably want to look to the future as she creates her own path."
King Charles was the one to give the pair the entities.
"As my Heir, William now assumes the Scottish titles which have meant so much to me. He succeeds me as Duke of Cornwall and takes on the responsibilities for the Duchy of Cornwall which I have undertaken for more than five decades," he stated. "With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the center ground where vital help can be given."
