Camilla Parker Bowles snatched Princes Diana's title.

The Prince of Wales and Camilla are in Ghana where they met King Otumfuo Nana Osei Tutu II at a Durbar and Tea with the Asantehene at Manhiya Palace. However, in what appeared to be a gaffe by Ghanaian officials, they referred to the Duchess of Cornwall as "Princess Camilla."

Daily Star shared a photo of the tarpaulin that read "The Centre For National Culture Kumasi Welcomes Your Royal Highnesses Prince Charles Prince of Wales, Princess Camilla Duchess of Cornwall." The titles were printed beside the royal couple's photo.

Camilla is never called princess, but she's technically the Princess of Wales because a woman married to a British royalty gets the female version of her husband's title. Since Prince Charles is the Prince of Wales, she's the Princess of Wales.

However, Camilla opted to be addressed as duchess instead of princess because the latter is strongly associated with Prince Charles' first wife, Princess Diana. Experts believe that she opted for the said style to not stir the Brits who don't like her.

During the said trip, the future king was spotted attending a church service without Camilla at Accra Ridge Church. He arrived in a light-colored suit, burgundy brogues and a silk handkerchief tucked in his jacket pocket. The British royal sat with Ghana's First Lady Rebecca Akufo-Addo. Although the Duchess of Cornwall was noticeably missing, she was set to be joining Prince Charles for engagements later that day.

Prince Charles and Camilla's visit to Ghana is the second leg of their tour of West Africa which came following the announcement that the heir to the throne will also succeed the Queen as the Head of the Commonwealth, which is made up of 52 nations.

"I am deeply touched and honoured by the decision of Commonwealth Heads of State and Government that I should succeed The Queen, in due course, as Head of the Commonwealth," Prince Charles said at that time. "Meanwhile, I will continue to support Her Majesty in every possible way, in the service of our unique family of nations."

In related news, Queen Elizabeth II was reportedly furious with Camilla for not giving Prince Charles and Princess Diana the chance to mend their broken marriage.

"She would not condone his adultery, nor forgive Camilla for not leaving Charles alone to allow his marriage to recover," Tom Bower wrote in his book "Rebel Prince: The Power, Passion and Defiance of Prince Charles."
