Camilla is not ‘step-granny’ to Prince William’s kids: book

All in the family?

Prince William is reportedly adamant that his three kids — Prince George, 9, Princess Charlotte, 7, and Prince Louis, 4, — not call Queen Consort Camilla “step-grandmother.”

William’s father King Charles married Camilla, 75, in 2005 — nine years after his divorce from the late Princess Diana.

Angela Levin, author of the new book, “Camilla: From Outcast to Queen Consort,” wrote how William, 40, has framed his children’s relationship to Camilla.

“William nonetheless has made it clear that Camilla is the wife of his father, but not a step-grandmother to his children, and that Prince George, his sister Princess Charlotte and Prince Louis have two grandfathers, but only one grandmother,” Levin wrote.

Kate Middleton’s parents, Michael and Carole, are grandparents to their children with Charles, 73, as grandfather.

William’s mother Diana died in a car crash in 1997. She and Charles married in 1981 and divorced in 1996.

Charles and Camilla had an on-again/off-again relationship throughout their lives. The couple met in 1970 at a polo match and eventually parted ways when they wedded their respective spouses.

Camilla has two children with her ex-husband Andrew Parker Bowles — Tom Parker Bowles and Laura Lopes. Both Parker Bowles, 47, and Lopes, 44, each have children of their own.

According to a biography about Charles written by Sally Bedell Smith, he began having an affair with Camilla in 1986.

In Andrew Morton’s 1992 book, “Diana: Her True Story,” Diana revealed that she knew about the cheating and felt jealous over the infidelity. When 1994 rolled around, Charles finally admitted to the affair and Diana famously donned her “revenge dress.”

In 1995, a BBC Panorama interview aired and Martin Bashir asked Diana if Camilla was a reason for her split from Charles.

“Well, there were three of us in this marriage, so it was a bit crowded,” Diana said.
