Watch Princess Charlotte forget to bow to Queen Camilla during the coronation concert

This is the adorable moment Princess Charlotte forgot to bow to her step-grandmother, Queen Camilla.

Last night, the Royal Family saw stars such as Lionel Richie, Katy Perry and Take That perform at the Coronation concert outside Windsor Castle.

As the oldest members of the royal family, the newly crowned king and queen were the last to take their seats in the royal box.

The couple sat in the center of the front row of the box, which meant they had to walk past the Prince and Princess of Wales and their two eldest children, Prince George, nine, and Princess Charlotte, eight.

When her grandfather passed her by, Princess Charlotte did her best to bow as a sign of respect to the new king.

But when she got back up, Prince William and Kate Middleton’s second child lost her footing for a split second.

After she came to, Charlotte looked at her big brother and dad to see if they had seen her little one tripping.

In doing so, Charlotte was accidentally turned away from Camilla as she passed – meaning she was too late to bow to the Queen.

Queen Camilla had witnessed Charlotte’s overturned bow and tried to reassure her step-granddaughter.

As she walked by, Camilla gave the young royal a gentle pat on the back, prompting Charlotte to smile back.

Later in the evening, the princess turned to her mother for help adjusting her wristband – which had come loose during the festivities.

Charlotte appeared to be struggling with the paper around her arm as she waved her Union Jack in the stands and looked lost before calling on the Princess of Wales.

Kate, 41 — who was effortlessly elegant tonight in a scarlet suit — was quick to help her daughter by tightening the rogue band so she could keep having fun.

After bowing to her grandfather, Princess Charlotte seemed to lose her balance for a split second.

She helped little Charlotte tighten it up before tuning back into the star-studded lineup.

The King and Queen took center stage in the concert – getting carried away by their family waving the Union Flag and dancing, singing and applauding Lionel Richie, Katy Perry and a spectacular Take That finale.

Charles III and his wife Camilla also laughed lavishly at Miss Piggy and Kermit the Frog, who even appeared with them in the royal box before the dais and Windsor Castle turned patriotic red, white and blue.

The pair were cheered everywhere by the 20,000-strong crowd, who cheered the King and Queen on three occasions as they arrived as the sun set for the show that beamed into homes in 100 countries around the world.

And when night fell, the royals put on their glow stick wristbands, stood up and started dancing to Lionel as he sang All Night Long.

Katy Perry released hits including Roar before Take That wrapped up the spectacular show with Shakespeare, ballet and a drone show that reflected the monarch’s love of the environment, culminating in a blue whale hovering above the castle.

At the finale, choristers from St George’s Chapel, Windsor Castle sang the opening of Take That’s song Never Forget, giving the show an uplifting finale.

Prince George and Princess Charlotte clapped along to the song before the king joined in – and there was a dancing queen, as Camilla moved to the music. The royal couple then held up their Union flags as the concert drew to a close, William tickling George’s nose with his own.

The King and Queen danced along to Take That’s performance of Shine as Princess George and his sister Princess Charlotte enthusiastically waved their Union flags.

In the final performance of the Windsor Coronation Concert, the band, who have not performed together in four years, ended with Never Forget – with Kermit the Frog dancing along.

Charles and Camilla laughed and chatted as they hopped along throughout, while Kate, Charlotte and George also got into the mood – as did the Duke and Duchess of Edinburgh.

William had slipped away so he could go onstage to pay a touching tribute to his father, telling him, “Dad, we’re all so proud of you.”

He also told King Charles that he had no doubt that the late Queen Elizabeth, his “very proud mother,” would look down “lovingly” from heaven on his coronation weekend.
