The Queen's Platinum Jubilee celebrations came to a spectacular end when she appeared on the Buckingham Palace balcony with her heirs, Prince Charles, Prince William and Prince George.
They were joined by Camilla, the Duchess of Cambridge, Princess Charlotte and Prince Louis to wave to tens of thousands of well-wishers who had gathered on The Mall earlier for the Jubilee Pageant.
The family could be seen waving to the crowds, before the National Anthem played and spent a very short time chatting before red, white and blue smoke popped out of a stage before they headed back inside the palace.
And professional lip reader John Cassidy has revealed why he believes the Queen seemed surprise during her balcony moment, especially at the end of a rousing version of God Save The Queen.

Dressed in a bright green coat with a matching hat and using her walking stick, the Queen watched on as people sang the National Anthem.
The Queen's appearance on the balcony was her third of the four-day weekend and comes after she was forced to pull out of Friday's Service of Thanksgiving and the Epsom Derby yesterday.
The royal finale comes at the end of a spectacular People's Pageant, which saw thousands of members of the public and celebrity national treasures parade around Buckingham Palace in fancy dress symbolising the seven decades of the Queen's reign.
George, Charlotte and Louis were among the special guests who watched the event from the royal box. They sat in the front row with parents William and Kate.
After stealing the show at Trooping of the Colour on Thursday with his incredible facial expressions, Louis once again entertained crowds by mucking about with the other young royals. He could be seen playing with his cushion, covering his eyes and dancing in his seat.
He was also seen tucking into some chocolate, covering his mum Kate's mouth with his hand and at one point was entertained by his grandfather Charles.
