Michael Jackson's children, Prince Michael, 12, Paris Katherine, 11, and Prince Michael II (Blanket), 7, took the stage during a group performance of 'Heal the World'.

After the song, Paris gave an impromptu speech from the stage surrounded by the Jackson family.

"I just want to say ever since I was born, Daddy has been the best father you can ever imagine,¿ she said through tears. "And I just want to say I love him so much."

Her aunt Janet Jackson then took her into her arms for a hug before the entire Jackson family then left the stage, closing the service that lasted more than two hours.

The moving tribute was especially startling because it marked one of the first times Jackson¿s daughter has ever been heard publicly.
