The 96-year-old monarch, who celebrated 70 years on the throne with a variety of special events in her honour, joined her close family on the Buckingham Palace balcony on Sunday (5 June).
The Queen, who sadly lost her husband in April last year at the age of 99, appeared to pay tribute to her beloved with a black mourning pin worn on her hat.
The Duke of Edinburgh endured a lengthy hospital stay in February 2021. He was treated at two London hospitals for an undisclosed infection in addition to a heart condition, before returning to Windsor the following month..
He retired from royal duties in 2017 and had effectively stepped back from public life, spent much of his time at Wood Farm on the Sandringham Estate in his final years.
Prince Charles and his wife Camilla, the Duchess of Cornwall, the Duke and Duchess of Cambridge and their three children Prince George, Princess Charlotte and Prince Louis were all pictured alongside the Queen on the balcony.
Although the Queen was forced to withdraw from several events over the weekend, she was able to watch a crowd made up of thousands of spectators sing the national anthem as the celebrations came to a close.
While the extended bank holiday weekend was to congratulate the Queen for seven decades of service, Prince Louis totally stole the show and people couldn't take their eyes off him and Princess Charlotte during one hilarious moment in which Charlotte was filmed telling off her brother during the pageant. Watch the clip below:
Later on during the pageant, Louis was seen climbing out of his seat to sit on Prince Charles's lap.
The four-year-old first stole the show during the Trooping the Colour ceremony on Thursday, with viewers obsessed with his antics on the Buckingham Palace balcony.
They watched as Louis covered his ears from the loud noise of the planes flying overhead and was pictured jumping in excitement and waving at the sky as thousands of onlookers down below watched in awe.
The youngest Cambridge sibling had to be watched with a close eye, although viewers loved catching a glimpse at the bonds between the three siblings.
In another funny viral moment, Louis became impatient and was photographed covering his mum’s mouth.
On Monday (6 June), Kate Middleton and Prince William broke their silence on their son's antics in a hilarious way.
“What a fantastic weekend of celebrations,” the Cambridges wrote on Twitter. “Seeing people across the nation coming together with family, friends and loved ones has been extremely special.
"Thank you to everyone who turned out to show their gratitude to The Queen and her inspiring 70 years of leadership. From the crowds on the Mall to communities hosting street parties up and down the country, we hope you had a weekend to remember.
"We all had an incredible time, especially Louis…"
