The celebrations for the Queen's 90th birthday began in a sea of colour under bright blue skies for her walkabout in Windsor.
Everyone was pretty excited as they lined the streets of her journey for the chance to catch a glimpse of, or even meet, Her Majesty.
There were dogs on people's heads.
Squirrels on heads..we think?
Corgis on cakes.
Sandra from Gogglebox was there.
And then the moment that everyone has been waiting for... the Queen arrived. Initially she waved to fans while flanked by the Duke of Edinburgh in the back of a Range Rover.
The Queen then met some of the hundreds of fans who had come out to meet her.
Great British Bake Off winner Nadiya Hussain baked a cake for the Queen. It was pretty impressive.
The Queen accepted presents too.
As all of the merriment was going on in Windsor there were celebrations around Britain.
Officer Cadets from Tayforth Universities Officer Training Corp doffed their caps to the Queen after carrying out a 21-gun royal salute at Stirling Castle.
And The King's Troop Royal Horse Artillery performed a 41 Gun Royal Salute at Hyde Park.
