The Royal Family will be taking time out of their day to remember the Queen Mother - who died exactly two decades ago today.
The Queen Mother was close with her grandchildren and great grandchildren, so made sure they would be well looked after once she passed away.
It's reported she put a large sum of money into a trust fund to be split between all of her great grandchildren, but as per an agreement, Prince Harry received more of the inheritance than Prince William.
So, when she passed away aged 101, the brothers had £14million to split between them, but as previously agreed the younger brother did better out of the deal.

The logic behind the Queen Mother's decision is based on how finances within the royal family work, reports The Mirror.
When the Queen dies and Prince Charles becomes king, William will likely become the new Prince of Wales.
This means he will inherit the Duchy of Cornwall, a private estate that funds the public, charitable and private activities of the heir to the throne. Harry, on the other hand, won't get any of this.
Harry's inheritance from both the Queen Mother and his mum, Princess Diana, had helped him to start his new life in California with Meghan Markle after they stepped down as senior royals in 2020.
The couple are now said to be a lot happier, living the dream life in the sunshine with their two beautiful children.
After the Queen Mother's death, Buckingham Palace revealed some details about her will after going to the High Court to try to keep it private.
Her estate was valued at between £50m and £70m at the time and was passed on to her daughter the Queen.
Many items from the Queen's private art collection were given to the royal collection and went on display at Buckingham Palace.
A statement released at the time read: "Queen Elizabeth The Queen Mother has bequeathed her entire estate (which mainly comprises the contents of her houses) to The Queen.
"In her will, she asked The Queen to make certain bequests to members of her staff, and these bequests will be subject to Inheritance Tax in the normal way.
"The Queen has decided that the most important of Queen Elizabeth's pictures and works of art should be transferred to the Royal Collection."
