The Queen delighted millions of spectators after making a surprise appearance on the Buckingham Palace balcony on Sunday evening.
The royal, who was dressed in green, waved to fans while standing alongside the Prince of Wales, Duchess of Cornwall and the Cambridge family.
Earlier, during the pageant, Prince Charles took the salute from members of the military as he represented his mother.
Although Her Majesty was not present for the event at the time, her hologram was included in the golden coronation carriage for the Platinum Pageant parade.
In an incredible piece of technological wonder, a hologram of Her Majesty from her coronation appeared waving to the crowd in 1953 to the delight of fans and the viewing public.
Prince William is also in attendance for the final showpiece of the weekend. Kate, Duchess of Cambridge is alsowatching on alongside Princes George and Louis and Princess Charlotte.
