Hayley and Leah have been live in London keeping you up to date on all the Diamond Jubilee celebrations.
They blogged throughout the action with the latest news and pictures.
On Sunday they got wet watching the Pageant. On Monday they saw the concert coming together.
And on Tuesday, they saw the Royal Family attending a service at St. Paul's Cathedral, followed by a carriage procession and flypast at Buckingham Palace.
The Queen's husband, the Duke of Edinburgh had to miss Monday and Tuesday's celebrations because he was taken to hospital with an infection. He's expected to stay there for a few days as a "precautionary measure", say staff at Buckingham Palace.
