The Duchess of Cornwall's son has revealed his children call Prince Charles "Umpa", as he shared details of what life is like when the future king is your stepfather.
Tom Parker Bowles was speaking to The Times as he launches his new book, Time For Tea, and said his children, now 13 and 11, grew up calling the prince "Umpa", while Camilla was known as "Gaga".
Parker Bowles, now an established food writer and critic, is the son of Camilla and Andrew Parker Bowles who were married in 1973.
Although Camilla and Prince Charles had previously dated, their relationship did not move to engagement in their youth, but they remained close friends.
Prince Charles is Parker Bowles's godfather, so has been in his life longer than as his stepfather.
By the late 1980s, Charles and Camilla had rekindled their relationship, and Parker Bowles recalled paparazzi being outside their home waiting to get pictures of his mother, when he was 13.
He was 18 when Diana lifted the lid on Charles and Camilla's relationship and then was at university, aged 19, when tapes of an intimate conversation between his mother and the prince were leaked.
Despite the difficult past, he is affectionate about Charles, who he said is "sweet and gentle" and "ahead of his time".
But he did not comment on the apparent rift between Charles and Prince Harry, and even said he did not watch Harry and Meghan's interview with Oprah Winfrey.
Parker Bowles told the paper: "I wasn’t around.
"What can I say? Families are never easy but they’ll work it out in the end."
He added: "I stay out of that. That’s nothing to do with me."

Camilla has previously spoken of her close relationship with her son and grandchildren. Parker Bowles's children are Lola, aged 13, and Freddy, aged 11.
As well as son Tom Parker Bowles, she has a daughter Laura Lopes, who has three children - Eliza, 13, and twins Gus and Louis, 11.
In July 2020, Camilla guest edited The Emma Barnett Show on Radio 5, before the presenter moved over to host Woman's Hour.
She told Barnett she was missing hugging her grandchildren, but that she'd adapted to becoming a Zoom granny.
They also called Parker Bowles during the show, with Camilla discussing what kind of mother she was.
Barnett took the opportunity to ask if his mother was a strict parent.
After hesitating a bit, he said: “My mother? Strict... no.”
Camilla replied: “You know when I’m cross.”
They also spoke about their differences in tase, with Tom saying he likes chilli and spiced food, but she prefers “plain” dishes.
He said: “We argue in the kitchen, she would say I was doing something wrong, I would moan her knives are blunt or not enough light, so it’s best if we keep separate.”
Camilla said: “Tom is a very good cook, and he is dead right, he loves everything very very hot, he adores chillies, I’m afraid to say I don’t.
“He complains about my kitchen, he says I’ve haven’t got the modern stuff, everything’s wrong, my knives are blunt.”
