Prince Louis shared a sweet moment with his grandad after he became restless during the Jubilee Pageant.
Future King Prince Charles rocked the cheeky four-year-old from side to side as he sat on his knee and they watched the show.
The four-year-old got restless while watching the lengthy parade - and was seen dancing during the sensational show - just after a cheeky encounter with Mike Tindall.
He previously kept royal fans entertained during Trooping the Colour, with his funny faces on the Buckingham Palace balcony - and cheeky questions for the Queen, his great-grandmother.

To the Duchess of Cambridge's amusement (and slight displeasure), he was seen wandering off from his seat, after seemingly getting bored.
Kate stroked Louis’s shoulder before he got out of his seat and walked to his grandfather.
One royal fan tweeted: "Prince Charles and Prince Louis have the best bond."
"Lovely to see Prince Charles in grandpa mode with Prince Louis today!," wrote another.
A third added: "Prince Louis and his grandpa Charles being the sweetest at the #PlatinumJubileepageant. It’s so lovely to see their bond."
Mia Tindall sat on her father Mike’s lap at one point in the concert, while Lena Tindall sat on her cousin Savannah Phillips’s lap.
Louis could also be seen pointing at Boris Johnson while looking confused, and covering his face with his hands.
Royals including Prince Charles, Camilla, and the Duke and Duchess of Cambridge will be watching from the royal box, although the Queen is not attending.
Other royals in the Jubilee Pageant’s box are the Prince of Wales and the Duchess of Cornwall and the Duke and Duchess of Cambridge.
The Princess Royal and Vice Admiral Sir Tim Laurence are also there with Princess Beatrice and her husband Edoardo Mapelli Mozzi, and Princess Eugenie and her husband Jack Brooksbank.
Anne’s son Peter Phillips is joined by his children Savannah and Isla, while Zara and Mike Tindall and the Duke and Duchess of Gloucester have also made an appearance.
Princess Eugenie could be seen bouncing son August on her knee - in his first public appearance.
The one-year-old is wearing a jumper with a Union flag on the front.
