BeatrixFan said:Well it's not incorrect to call them The Prince and Princess of Wales. Because that's just what they are. For years people were able to call Diana 'Princess Diana' with no problems at all - so I intend to use Princess Camilla if I like.
It is incorrect to refer to Camilla as The Princess of Wales because her style and title is Duchess of Cornwall. Similarly, it is incorrect to refer to Louise Wessex as Princess Louise because her style and title is Lady Louise Windsor.
The Queen did not object to "Princess Diana" because she was the mother of a future king, however, technically she was no longer a princess of the UK after the divorce. She was HRH The Princess of Wales while married.
