Kate Middleton was seen giving her children a telling-off while they were waving to crowds of royal fans during the Trooping the Colour parade.

It comes as Prince Louis stole the show once again at Trooping the Colour today as he saluted the crowds who came out to watch King Charles' first birthday parade.
The youngest son of the Prince and Princess of Wales was in attendance at the Trooping the Colour ceremony to celebrate the birthday of the monarch.
Many royal fans were fixated on five-year-old Louis who could be seen saluting the crowds as well as pulling a range of excitable faces.

His "unique" waving style also made an appearance as fans on Twitter were left gushing over how he looked like he was doing an impression of window wipers.
The last time fans saw his wave was seen on the balcony was at the coronation of King Charles III on May 6.
Louis was seen tapping his hands down on the side of the balcony to mimic the sounds of the marching band's drums and waving his hands from side to side.
Fans immediately took to Twitter to share their opinions on the little one's antics saying he "looked bored".
