Princess Kate and sister Pippa's schoolgirl antics revealed by James Middleton

James Middleton has revealed what his two sisters, the Princess of Wales and Pippa Middleton were like during their school days.

In his new book, 'Meet Ella: The Dog Who Saved My Life', James gave an insight into his childhood and shared that both Kate and Pippa were "exemplary students" at school.

Describing his sisters as "accomplished", James spoke of their close bond and noted that he was a lot different to them during his school days.

He penned in his book: "Naturally, Catherine and Pippa, being exemplary students, managed to get through their entire school lives without a single demerit, but I amassed a handful of them every term."

The 37-year-old - who is now a father of one - added: "So while the female Middletons would be applauded for being helpful to teachers – opening doors and carrying books for them – I’d undo all their kind deeds by scampering along the corridor instead of walking because I was late for a lesson. (Two bad order marks for the price of one there.)"

He also added: "And while Catherine and Pippa got full marks for spelling tests and top grades for essay writing, I lagged behind on both counts, accruing a batch of misconduct marks for my below-par schoolwork."

As an insight into his, Kate and Pippa's childhood, James recalls being "dragged" along to their sport matches.

With Kate known for her sporty personality, he added: "Every time I was dragged along to spectate at one of their sports matches, I’d sidle off and beg the headmaster’s wife to let me take her beautifully groomed Old English Sheepdog for an amble around the grounds. These innocuous-sounding walks escalated into Famous-Five-style adventures (although in our case, we were an intrepid duo).

"At the final whistle, as my sisters emerged triumphant or deflated from their sporting feats, a bedraggled, mud-flecked vision – half human, half canine – materialised from a nearby copse, having splashed heedlessly through puddles and streams for the past hour."

James's love of animals has led to him setting up his own dog food and lifestyle company, Ella & Co.

His beloved late dog Ella also introduced him to his wife, Alizee Thevenet - whom he married in 2021.

The couple welcomed their son Inigo - now aged one - in September 2023.
