Earlier this year, The Duke of Cambridge told how one of the few things the children fight about is who gets to choose the music in the background.
He also revealed how Charlotte likes to play the song Waka Waka by Colombian pop star Shakira.
He said: "What I've been amazed by is how much my children already have inherited my family's love of music.
"Most mornings there's a massive fight between Charlotte and Prince George as to what song is played.
"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."
He added: "It's a really happy moment where the children just enjoy dancing, messing around, and singing."
Charlotte has been seen in public on two occasions recently.
She was with her parents and brother Prince George at the Easter Sunday service at St George's Chapel in Windsor on April 17.
On March 29 she was with her parents and George for the Duke of Edinburgh's memorial service at Westminster Abbey for what was the Cambridge children's first outing at a major church event.
