With her brief speech, 11-year-old Paris Jackson also shocked the event's organizers, who сказал(-а) her appearance was not a planned part of Tuesday's star-studded tribute to the "King of Pop" at Los Angeles' Staples Center.

"Ever since I was born, daddy has been the best father Ты could ever imagine," she said, fighting back tears as relatives consoled her.

"And I just want to say that I Любовь him so much," she сказал(-а) as she burst into tears and sought refuge in the embrace of family members. Watch her emotional goodbye »

For many watching, Paris' appearance marked a rare glimpse of a child who has spent most of her life shielded from the public.

Born to two mothers -- Jackson's ex-wife Debbie Rowe and an unidentified woman who reportedly served as a surrogate -- Jackson's three children lived and traveled the world with him, their faces often covered by veils and masks when appearing in public.

In its execution, the speech appeared to be a surprise to those onstage and off.

"It was a surprise they were there. All of us who know them were delighted they were strong enough to come and feel this Любовь and great outpouring for their dad," Kenny Ortega, the choreographer ("Dirty Dancing") who was directing Jackson's "This Is It" comeback concerts in London, England, told CNN's Campbell Brown. "We would've never expected that they had the strength. It was beautiful." Watch Ortega express his surprise at Paris Jackson's tribute »

Ortega, a longtime Jackson colleague who helped Дизайн the singer's 1990s tours, сказал(-а) planners left the end of the Показать open for family members to speak if they wished to, but he was surprised when the Jackson clan -- among them, his siblings and children -- went onstage for the two last songs, "We Are the World" and "Heal the World."

Marlon Jackson told the crowd that his sister, pop звезда Janet Jackson, wished to say some words. Instead, Janet appeared to encourage Paris to come вперед from the sea of black dresses and Форс-мажоры and take the microphone, adjusting it and stroking the child's hair as Paris delivered her words.

Ortega сказал(-а) he was touched by Paris' speech.

"Michael was so close with these beautiful children," he said.

"Little Paris was his biggest fan. ... A little girl couldn't Любовь her papa more."

The heartfelt display sparked a groundswell of emotion in the auditorium and around the world, where millions of viewers watched the service on Телевидение and the Internet.

"The saddest moment was when Michael Jackson's daughter spoke," сказал(-а) Angelina Martinez, who attended the service with her daughter, Jessica.

"She was really in pain. Everybody was crying inside," she said. "It was beauty combined with sadness."

Attendees, performers and speakers alike struggled for composure throughout the two-plus-hour event, which featured performances from Lionel Richie, Jennifer Hudson and Usher.

But to many, Paris' tribute cast Jackson in the one role few have experienced him as: a father.

"It was very, very touching, and really it was an example of the good parent Michael was, because when I was at Neverland and with the kids he really was a good loving father -- they had a fantastic relationship, and they were very close-knit," Stuart Backerman said.

"So to see Paris come on in such an emotional moment and obviously give her сердце out to her father was very, very touching."

Others saw the tribute as a whole as Jackson's final legacy to his children.

"There are those I feel in years to come, will try to distort him to his children ... and not understand that the real challenges that Michael Jackson had to seriously face and did face and make a difference," the Rev. Al Sharpton said.

"And I thought it was very important to put in context for his children what he dealt with in history and what he was able to do."
