The young Princess enjoyed the fifth day of the Games with the Duke and Duchess of Cambridge on her first engagement without her siblings. Charlotte, 7, revealed that her favourite sport is gymnastics and later managed to meet some of the gymnasts who competed.
She also enjoyed watching a hockey match and swimming heats before the Cambridges attended another engagement with SportsAid.
The Princess was seen with her hair in plaits with a sweet navy and white striped summer dress with a white peter pan collar and sandals.
Charlotte caught the attention of royal fans during the sporting event as she pulled faces much like her younger brother Prince Louis, and also clapped and smiled while sitting in the stands.
The royal trio attended the swimming heats at the Sandwell Aquatics Centre in Birmingham where the cheeky Princess was seen rolling her eyes at a remark from Prince William.
The family supported and encouraged freestyle hopeful Luke Turley as he competed for England in the 1,500-metre freestyle.
Following a busy day of engagements, the Duke and Duchess of Cambridge wrote on their Instagram account: “Thank you Birmingham!
“Athletes, mascots, and an amazing atmosphere…an unforgettable day for all of us at #B2022!
“A real highlight was going behind the scenes with @teamsportsaid and the @officialteamengland Futures where the next generation of athletes and support staff are helped to perform at their best, handle pressure and make the most of their experience at major Games.”

“Kate and William are very generous with how much they share their children with us.”
