It's a very special day in London today, Prince William and Prince Harry will mark the 10th anniversary of their mother's death with an event to celebrate her life.
The Concert for Diana, which would have been Diana's 46th birthday, will be one of the first events to take place in the new Wembley Stadium.
Sir Elton John opened the event with a performance of 'Your Song' before introducing the two princes, who entered to a standing ovation.
The royal princes took to the stage in front of 63,000 thousand people at Wembley Stadium at the start of the special gig they have organized in memory of their mother.
“This event is about all that our mother loved in life - her music, her dancing, her charities and her family and friends,” said William, 25. “We just want you to have an awesome time and enjoy the line-up.”
Harry said: “It’s great to see so many of you here supporting this very special show.”
Prince William's ex girlfriend Kate Middleton was also in attendance, further adding rumor that the pair has reconciled. (We're crossing our fingers for that one)
The concert features a line-up of acts including Lily Allen, Duran Duran, Take That, Kanye West, and Tom Jones.
