Prince George and Princess Charlotte stole the show Saturday at their second appearance during Queen Elizabeth II's Platinum Jubilee.

George, 8, and Charlotte, 7, joined their parents, Prince William and Kate, Duchess of Cambridge, on a visit to Cardiff Castle, where they met performers and crew taking part in Saturday night’s Platinum Jubilee concert at the castle.

George and Charlotte visited the castle without their younger brother, 4-year-old Prince Louis.

Louis joined George and Charlotte and the rest of the royal family on Thursday for Trooping the Color, the kick-off to their great-grandmother's Platinum Jubilee celebrations.

On Saturday, George, dressed in a blazer like his dad, and Charlotte, wearing a button-down coat over a dress, like her mom, were seen smiling and waving at the public who lined the streets for their appearance.

The siblings held the hands of William and Kate, who were each spotted at different times, pointing things out to their kids.
