Queen Camilla is currently on a royal tour of Australia and Samoa with King Charles, but her family will not be expecting WhatsApp replies anytime soon. In a new interview, Camilla's son, Tom Parker Bowles, revealed that his mother hates using her cell phone, especially WhatsApp.

In an interview with Woman & Home (via the Express), Parker Bowles discussed how he stays in touch with his mother when she is traveling for work. She works more,” he said. She's always working pretty hard, so I call my mom and she doesn't pick up, and I watch TV and think, 'Oh, she's in Jersey,'” he continued.

Another reason Parker Bowles finds it difficult to keep track of her royal mother is that she refuses to update her cell phone. Asked if the Parker Bowles family has a WhatsApp group, the food writer said, “We do - my children, my sister, my cousins. I think it's for security.”

Although it is impossible to keep in touch via WhatsApp, Parker Bowles' children seem to love spending time with their royal grandparents. Parker Bowles told “Love Your Weekend” (via the Express), “The kids, of course, know nothing. So they've grown up with this man they all love and think is wonderful, the king, who is called 'Uppa'”

During promotion of his new book “Cooking and the Crown: Royal Recipes from Queen Victoria to King Charles III” ("Cooking and the Crown: Royal Recipes from Queen Victoria to King Charles III (Cooking and the Crown: Royal Recipes from Queen Victoria to King Charles III), this food writer elaborated on what it is like to be Queen Camilla's son. He said, “Whenever someone meets my mother, they always go to ....... I mean, as any son would say, she's the kind of person you love to go to dinner with,” he told The Times.

Parker Bowles continued. We're going to have our disagreements. It would be very strange if we all agreed. It's weird. Certainly I would annoy her from time to time.”
