“SHE’S THE ONE WHO KEEPS THEM IN LINE.” 👑🥹 — EXPERT CLAIMS PRINCESS CHARLOTTE PLAYS A SURPRISING ROLE BEHIND THE SCENES As Prince George celebrates his 13th birthday and prepares for a major new chapter at Eton College, royal watchers are taking a closer look at the unique bond he shares with Princess Charlotte and Prince Louis. According to a body language expert, Charlotte’s quiet confidence has become an important source of support for both of her brothers during public appearances.

It is an exciting time for Prince George — who is today celebrating his 13th birthday. And not only that, the young royal is looking forward to starting at Eton College in a matter of weeks.

And while he now embarks on new adventures in his teenage years, one body language expert has opened up about the key role his younger sister, Princess Charlotte, plays in keeping the future monarch “in line”.

Judi James shared her unique insights on a Channel 5 documentary called Prince George at 13: The Next Generation.

And despite being younger than George, Judi said the 11-year-old plays a pivotal role among the three siblings, as demonstrated in some subtle gestures she has noticed over the years.

She explained: “We do see Charlotte keeping an eye on both of her brothers. What I found really fascinating isn’t so much that she is doing that, but for me, it is the way that when she does nudge them and tap them, they both fall into line.

“Children of that age, normally if a younger sibling says ‘put your arms down,’ [they’ll reply] ‘who do you think you are?’

“But they absolutely take it and I think that’s going to be very important when it comes to the dynamic because they will see that as a form of support.”

Judi compared the relationship between George and Charlotte to that of King Charles and Princess Anne.

She said Anne was the more confident sibling and she believes this also rings true for Charlotte.

“She seems to absolutely get protocol,” Judi added. “She knows what needs to be done.

“I don’t think either of them [George or Louis] have got hugely strong attention spams, they will be watching the planes or talking about something. So I think that helps them relax a little bit because they know that if they are doing anything wrong, they have got their sister there, who is usually in the middle of them.

“So in a way, I think it’s probably she goes out being the keeper of the choreography so they don’t have to, but at the same time, they know that if they do anything wrong, she will be there to correct them.”

Charlotte and Louis, eight, both go to a private preparatory school in Berkshire called Lambrook, which is where George had his final day earlier this month.

However, George will go to Eton in September, just like his father did, and he will have the choice to select from 28 subjects, including nine modern and classical languages.

William is said to be “thrilled” that George is attending Eton but for now all focus will be on his birthday celebrations.

Prince George at 13: The Next Generation will air on Channel 5 on Saturday July 25 from 9pm
