The Princess of Wales and Princess Charlotte proved they're just like any other mother-daughter duo as they hopped on the train for a girls' day out on Saturday.
Catherine, 44, and her 11-year-old daughter were spotted by a fellow commuter as they travelled on the apt Elizabeth line through Central London, with a source telling HELLO! that Charlotte looked almost "amazed" as she looked around the carriage.
The pair were seen seated on TfL's newest tube line – opened during the late Queen Elizabeth II's Platinum Jubilee year – with their security detail, and surrounded by other members of the public.
A source tells us: "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.

Catherine looked to be wearing a burgundy outfit and matching heels for their outing, with the pair disembarking at Tottenham Court Road.

While the Princess of Wales was a regular on the tube in her pre-royal days, it marked a rare appearance for Princess Charlotte, who is in Year 8 at Lambrook Preparatory School in Berkshire. Typically, the royals are chaperoned in motorcades or utilise their private helicopters.

The royal, who was pregnant with Prince George at the time, admitted during the engagement that she "missed" travelling on public transport.
The Prince and Princess of Wales also surprised fellow commuters when they rode on the Elizabeth line for the first time to travel to a pub in Soho to learn how London workers were preparing for King Charles's coronation in 2023.
Down-to-earth royals
The late Princess Diana insisted that her sons, Prince William and Prince Harry, experience as normal as upbringing as possible when they were children.
Former royal protection officer previously told HELLO! in 2022: "Although the boys had nannies, she was a hands-on mum and was always with them in their nursery or bringing them down to the kitchen for breakfast.
"They were allowed to have their friends for sleepovers and she'd let them bring them on holidays, too… She took them to Thorpe Park – where they had to queue for the rides like everyone else – a London bus and the underground, and to burger bars and restaurants such as Bill Wyman's Sticky Fingers.

Ken also revealed in his 2017 book, Guarding Diana, that Harry requested to ride on one of London's famous red buses, with the bodyguard arranging for them to travel on a Routemaster instead of being chauffeur-driven to Smollensky's Balloon restaurant on The Strand in 1992.
