How the little royals stole the show (again) at the Queen's birthday celebrations.

It may have been the official celebration for the Queen’s 92nd birthday – but it was the littlest royal family members who stole the show.

As the royal family stepped out onto the Buckingham Palace balcony at Trooping the Colour, the Queen’s annual birthday celebration, the children’s antics were in full view.

After Prince William and Kate Middleton’s son, four-year-old Prince George continued to talk and sing during the ceremony, George’s older cousin, seven-year-old Savannah Phillips, resorted to hilariously covering his mouth.

The cheeky prince was also seen ducking down below the balcony wall as his family watched the Royal Air Force fly past.

Three-year-old Princess Charlotte was also caught on camera after a fall on the balcony. Luckily her mum, Kate Middleton, was there to comfort her.

It's not the first time the royal children have stolen the show at Trooping the Colour.

In one balcony appearance, Prince Harry famously stuck his tongue out at photographers at the annual event.

Although the Queen celebrated her actual 92nd birthday in April, her public birthday is celebrated every year on the second Saturday of June.

According to the royal family's website, the event involves over 1,400 parading soldiers, 200 horses and 400 musicians.
