Princess Charlotte has been seen out and about breaking a royal rule alongside her mother, Kate Middleton, in a rare appearance over the weekend.The 11-year-old, who shares siblings Prince George, 13, and Prince Louis, eight, is usually kept out of the public eye while they’re at school, so Charlotte’s rare trip on London’s Elizabeth line with Kate was a surprise sighting for commuters.The mother-daughter duo were spotted travelling through central London on Saturday (10 October), accompanied by security but sitting among members of the public.A fellow passenger told HELLO!: “They spoke to members of the public sitting across from them. They had security with them, and Catherine held Charlotte’s hand getting off at Tottenham Court Road. The security didn’t make it obvious they were there, and they tried to make it as ‘normal’ as possible.”

The source added: “Catherine had her phone with her and was looking at her phone for a couple of minutes. They seemed very relaxed and were chatting together, smiling. It was a brief interaction with people opposite them, but they seemed very happy.”Charlotte reportedly looked ‘amazed’ as she took in the carriage before getting off at Tottenham Court Road.It’s not known where they were headed, but Kate and Charlotte have previously enjoyed mother-daughter outings to the ballet.Back in 2024, Prince William opened up about Charlotte’s interest in dance while meeting 10-year-old student Ruby Davies.”Charlotte loves her dancing and performing as well, so I’m going to show her your video when I get home, see where I’ve been today,” the future King told her.
