Only a few weeks ago she was having a play date with the children of one of the most famous tennis players in the world - Roger Federer - and now it's been revealed that the young princess is a natural in the courts.
A source told the Sun that Kate and William, who are currently expecting their third child, signed Charlotte up for tennis lessons at the exclusive Hurlingham Club, in London.
The young princess is said to have a natural talent for tennis
According to their report, the two-year-old has loved practicing the sport so far and has a 'natural' talent for it.
'Kate and William decided the Hurlingham was the perfect place for Charlotte to start, the source told the publication.
'She might not be three until May but they were convinced she'd love it and so far she has. She seems a bit of a natural.'
However, the fact that Charlotte's parents are not members at the very exclusive club is reportedly annoying some of the patrons, who think the princess should not be given special treatment and be allowed to play there.
'Unfortunately some patrons feel Charlotte shouldn't be allowed to play there. Club rules are usually very rigid, and they don't see why exceptions should be made, even if they happen to be royal,' the source said.
Tennis is not the first hobby to be taken up by Prince George's little sister. Despite being only two, Charlotte has also been taking dance lessons, a passion she inherited from her grandmother, Princess Diana.
Her mum revealed Charlotte's love for dance during a visit to Princess Diana's memorial garden in London to mark the anniversary of her death, in August, where she said that 'she absolutely loves it'.
Charlotte has also been taking dance lessons
Last year, the Duchess of Cambridge also revealed that Charlotte really loves horses while speaking to equestrian triple-gold medallist Natasha Baker at a royal event.
'I asked her how the children were and she said Charlotte is really enjoying her riding which is great to hear and I said we may see her here on a line-up in 20 years time,' Natasha said.
'She emphasised that Charlotte has this passion about horses and although she doesn't echo it, she'll do her best to champion and encourage it.'
Despite her very young age, it sounds like little Charlotte has inherited her family's many talents!
