The Duchess of Cornwall regularly leaves her husband and escapes to her old country house at Ray Mill House in the Cotswolds where she is free from the red carpet world, Prince Charles' demanding ways, and being on show at public events, the 'Daily Star' reported.
Camilla revealed her secret getaways to her hairdresser confidante Jo Hansford, who has been with her for 20 years.
Jo said: "Ray Mill House is her escape. She likes to be in her own home. With that kind of life how can you ever be a normal person? He was born into it, she wasn't, she came into it much later in life.
"Why would he want to take on all her family, then feel uncomfortable being in another situation? That escape is fantastic from her point of view."
In fact, Buckingham Palace officials are also "concerned" over 64-year-old Camilla's disappearing acts, which take place every 10 days. And, the 63-year-old heir to the British throne has discussed the issue with her, the newspaper said.
A royal aide said: "This is causing concern about the future. She goes off at least once a week or every 10 days to escape. Charles is worried and irritated and has spoken to her. But she thinks he is being unfair.
"He is used to getting his own way but Camilla feels that now, within reason, she is going to lead her own life. They are not talking about divorce, they are mature people. This is how they make their marriage work."
However, a spokesman for Charles and Camilla said: "They are not leading separate lives, they do joint engagements and individual engagements to maximise the impact the royals have."
