Prince William and Prince Louis appeared to be having a brilliant time watching the military procession on Monday.
The Prince and Princess of Wales stepped out with their youngest, who recently turned seven, as well as George, 11, and Charlotte, 10, to mark the start of four days of events to commemorate the 80th anniversary of Victory in Europe Day.
And while all three of the Wales children were engrossed in the action, little Louis and his dad sat together and bonded beautifully while watching the impressive parade descend on The Mall.
According to professional and expert lip-reader Jeremy Freeman, at one moment during the parade, the Prince of Wales was keen to point out a drummer to his youngest son and says with a smile: "This man over there, look how proud is he… this one there," before making a comment about his hat to Louis.

The Wales's important day in the royal calendar
VE Day is always a poignant and important day for the royals, particularly the monarch, but it also serves as a fantastic opportunity for Prince William and Kate, to pass down the significance to their three children.
While Prince George, Princess Charlotte and Prince Louis have been to other significant royal events that include a Buckingham Palace flyover, such as Trooping the Colour, this is the first major anniversary for VE Day that they have attended.

Then, in 2020, for the 75-year anniversary, the country was under lockdown regulations due to the coronavirus pandemic, which prompted the late Queen to mark the occasion virtually.
Before pointing out the drummer to Louis, William's three children walked to their seats and greeted the veterans who were sitting alongside them.

Following the flypast, King Charles and Queen Camilla headed to the Buckingham Palace Garden to host a tea party for veterans.
Prince William and Kate's younger two children didn't join them, however, Prince George was seen engaging with veterans alongside his parents.

The tea party will welcome British and Commonwealth Armed Forces veterans and women's Royal Navy Wrens, as well as senior royals and Prime Minister Sir Keir Starmer, to mark the momentous day in history.
