Princes William and Harry have been speaking about how they hope their mother's legacy lives on through the young people involved in the charity which takes her name.
At St James' Palace on Thursday, they presented twenty Legacy Awards to young people involved in the charity, The Diana Award, in the twentieth year since she was killed.
Before the ceremony, the Duke of Cambridge spoke of how much this award means to them and to the memory of Diana, Princess of Wales.
Prince William told the audience:
"She was taken at only 36 - just slightly older than I am today. Of course we can never know what our mother would have gone on to do. But in one sense, Harry and I feel that our mother lives on in the countless acts of compassion and bravery that she inspired in others."
In August, the brothers will mark the 20th anniversary of their mother's death in that car crash in Paris.
The Diana Award was set up to honour her belief that young people have the power to change the world in which they live.
The award scheme has selected 20 young people from the UK, USA, Canada, India, Belize and UAE who the charity says have had 'a monumental impact on society'.
Prince Harry also spoke at the event saying: "One of the things our mother taught William & I was the value of doing good when no one is watching"
Harry also told some of the recipients: "I cannot believe how young you all are, most of you are still at school. When you get some spare time on your hands you're saving lives and inspiring people.
"You should be absolutely proud of what you've started and what you've achieved, you're still in your teenage years - don't stop now guys."
