Prince William reveals what causes 'massive fights' between Charlotte and George every morning

Prince William has revealed the cause of "massive fights" between his two eldest children every morning. 

Speaking on an upcoming episode of Apple Fitness+'s Time to Walk audio walking series, the Duke of Cambridge explained that music is a critical part of the family's routine - and often prompts conflict. 

"Most mornings there's a massive fight between Charlotte and George as to what song is played," he said, according to Entertainment Tonight.

"And I have to, now, basically prioritise that one day someone does this one, and another day it's someone else's turn. So George gets his go, then Charlotte gets her go. Such is the clamour for the music."

Despite the tensions around choosing tunes, William emphasised how happy it made him to see his children dressing up and dancing and singing in the kitchen - including the youngest of the brood, Louis. 

"There's a lot of hip movements going along. There's a lot of dressing up. Charlotte, particularly, is running around the kitchen in her dresses and ballet stuff and everything," he said. 

"She goes completely crazy with Louis following her around trying to do the same thing. It's a really happy moment where the children just enjoy dancing, messing around, and, and singing."

William also recalled his late mother Princess Diana's love of music and how she would sing "at the top of her voice" while driving him and Prince Harry to boarding school. 

"My mother used to play all sorts of songs to kind of while away the anxiety of going back to school. And one of the songs I massively remember and has stuck with me all this time, and I still, to this day, still quite enjoy secretly, is Tina Turner's 'The Best' because sitting in the backseat, singing away, it felt like a real family moment," he said.

"My mother, she'd be driving along, singing at the top of her voice. And we'd even get the policeman in the car, he'd be occasionally singing along, as well. 

"You'd be singing and listening to the music right the way out into the gates of school, when they dropped you off. When I listen to it now, it takes me back to those car rides and brings back lots of memories of my mother."
