PRINCESS Charlotte stole the show as she joined big brother George, mum Kate Middleton and dad Prince William at Cardiff Castle today.
The Cambridges travelled to Wales to meet entertainers staging a show to mark the Queen's Platinum Jubilee - and Charlotte captured spectators' hearts as she greeted guests.
As she stepped out of the car, royal watchers were convinced they spotted the seven-year-old attempting a curtsey in front of a navy cadet before he shook her hand.
Taking to Twitter, royal reporter Rebecca English wrote: “I think #PrincessCharlotte went to do a little curtsey, bless her! #PlatinumJubilee.”
And others were quick to agree, with another tweeting: “Yes, that's what I thought too! What a darling!”
“😊 she is still figuring it all out,” added a third.

Another wrote: “She won’t have done much hand shaking and will mainly have seen it when people shake her parents hand while curtsying (if female) so automatically went to do it when he shock hands and just managed to stop herself.”
Kate and Wills, along with George, eight, and Charlotte are due to watch rehearsals and meet some of the acts taking part in the celebrations, including Welsh singer Bonnie Tyler.
Bonnie was last week made an MBE in the Queen's Birthday Honours for her services to music.
The royals will also meet weatherman Owain Wyn Evans, best known for his role on the nightly news programme North West Tonight and The One Show.
