Camilla Parker Bowles is not called a princess because of one possible reason.

The Duchess of Cornwall is technically a princess too. Camilla earned the female version of Prince Charles' titles following their wedding. And since the future king is the Prince of Wales, she's actually the Princess of Wales. However, according to a royal expert, she's not addressed using the title princess because she doesn't want to cause ill will for herself as the title is strongly associated with Princess Diana.

"Camilla was not popular or well liked, [though] this has changed a lot since the marriage as Camilla has taken on a lot of patronages and Charles is a lot happier," royal commentator Marlene Koenig said (via InStyle). "Still, [there was] a lot of tension and anger among a certain element of the population — so it was decided that Camilla would be styled as the Duchess of Cornwall, even though, of course, she is the Princess of Wales."

Camilla has slowly gained the warm support of the public over the years. However, her title has never changed except for one recent event in Ghana where she was addressed by her princess title.

The Prince of Wales and Camilla are currently in Ghana where they met King Otumfuo Naa Osei Tutu II at a Durbar and Tea with the Asantehene at Manhiya Palace. They welcomed the British royals with a large signed printed with Prince Charles and Camilla's faces and a message that read: "The Centre For National Culture Kumasi Welcomes Your Royal Highnesses Prince Charles Prince of Wales, Princess Camilla Duchess of Cornwall."

In related news, many believe that Camilla is a positive force for Prince Charles. The future king is called "the boss" and dubbed as "pampered prince" due to his bizarre demands. He reportedly asks someone to do even the simple chores like putting toothpaste on his toothbrush. However, with Camilla, the heir to the throne has become "a helluva lot easier and happier."

"She's made a massive difference in him," a longtime correspondent told Vanity Fair. "He's much more relaxed now. They are always laughing and chatting, they have great affection and humor between them."
