The Queen's Platinum Jubilee concert opened by her and Paddington Bear is being hailed as the "best thing to happen this decade".
The Party at the Palace rounded up the third day of a four-day holiday weekend in the United Kingdom dedicated to celebrating her 70 years on the throne.
Rock band Queen, Sir Elton John, Duran Duran, Diana Ross, Rod Stewart, and more performed for more than 22,000 people gathered down The Mall outside Buckingham Palace on Saturday night (local time).
While the 96-year-old monarch didn't attend the concert, she captured people's hearts by appearing in a surprise video recorded with Paddington.
In the two-and-a-half minute clip, Paddington is having tea with the Queen and offers her a marmalade sandwich he had stored in his signature red hat.
"I always keep one for emergencies," he said, to which the Queen replied: "So do I."
She opened her handbag and pulled out her own marmalade sandwich and remarked: "I keep mine in here."
Paddington then congratulated the Queen on her 70-year reign, saying: "Happy Jubilee, ma'am. And thank you for everything."
"That's very kind," the Queen replied.
The sequence ended with both the Queen and Paddington using a spoon to tap out the beat of Queen's 'We Will Rock You' on a china teacup as the band themselves and the Corps of Drums from the Bands of Her Majesty's Royal Marines started the song on the main stage outside Buckingham Palace.
Viewers at home appeared to be delighted at the Queen and Paddington's appearance together.
"Why am I crying real tears at the opening of the Jubilee concert at Paddington and the Queen?" one person said on Twitter.
"The Queen having tea with Paddington, having a marmalade sandwich in her handbag and playing 'We Will Rock You' with a spoon on her teacup is the best thing to happen this decade," another said.
"Everyone's talking about the Queen and Paddington Bear, but spare a thought for the person who had to make the request, 'Would you have tea with a CGI bear, pull a sandwich out of your handbag, then play 'We Will Rock You' on a teacup?'," a third said.
A Buckingham Palace spokesperson said it shouldn't come as a surprise the Queen took part in the sketch since she's "well known for her sense of humour".
"There was an interest in the filming and animation process and the opportunity to invite a famous bear to tea was just too much fun to miss," they said.
"While The Queen may not be attending the concert in person, she was very keen that people understood how much it meant to her and that all those watching had a great time."
The final day of Jubilee celebrations on Sunday will see more than 10 million people take part in Big Jubilee Lunch picnics and there will be a musical and creative public pageant involving 10,000 people.
