FACTBOX-What the stars said about Diana at concert

(Reuters) - An international lineup of pop stars paid tribute to Princess Diana on Sunday at a concert watched by her sons Princes William and Harry and a crowd of 60,000.

Here is what the stars and politicians said about Diana:

FERGIE (before concert):

"I just remember her being a humanitarian, using her celebrity to make people notice things like AIDS, a lot of things with children ... she really gave out."

PRINCE WILLIAM (on stage):

"This event is about all that our mother loved in life -- her music, her dance, her charities and her family and friends.

"For us this has been the most perfect way of remembering her and this is how she would want to be remembered."

KIEFER SUTHERLAND (on stage):

"We've all seen her ... as a princess, as a loving and dedicated mother and as one of the great, great, great icons of giving. On this day, July 1, which was to be her 46th birthday, we get to celebrate her through the music that she loved played by musicians that she admired."

BILL CLINTON (televised):

"I remember Princess Diana as a humble person -- despite her fame and position she never stopped fighting for others -- for being one of the first to draw attention ... to the crisis of HIV and AIDS, to campaigning against landmines in war-torn regions. Diana was an effective and relentless advocate for those in need."

TONY BLAIR (televised):

"Princess Diana touched our lives in a way we will never forget, but for William and Harry she was their mother, though they had to share her with the whole world. At times before her death, and since, this must have been very hard for them, so I would like to pay tribute to them.

"Despite being so clearly a princess, she was also so obviously a human being. People knew that and they loved her for it, and I think that in William and Harry the qualities that made Diana special live on."

SEAN "DIDDY" COMBS (in BBC interview):

"She was somebody that I had so much respect for, I was a huge fan of, just her grace and her beauty and her compassion as a great example for the world. I lost my friend 10 years ago and I made a song called 'Missing You' and from that time on I would also dedicate the song to her whenever I would do it live in concert. She really touched me."

DAVID BECKHAM (in BBC interview):

"I think Princess Diana made such a huge impact on everybody's life, not just in our country ... but everyone around the world, so I can understand and believe the hype that's been involved in this."
