After Michael Jackson's public memorial Tuesday in Los Angeles, Michael's close friend Lou Ferrigno tells ET about the emotional day as the world said goodbye to the King of Pop.

Ferrigno, who was training Michael to get in shape for his upcoming 50-concert stint in London, tells ET that although he was shocked by the star's sudden death, the public memorial was beautiful and touching.

"It was beautiful, the whole thing -- the production," he says. "When they brought the casket in, Michael was in the casket and Michael came to be with us. It was wonderful because it wouldn't be the same if the casket wasn't there. It just broke everyone's heart to see the family, the brothers wheel in the casket, it was beautiful."

Ferrigno also tells ET about the way the of King of Pop touched so many peoples' lives, and about Michael's daughter Paris - Michael Katherine Jackson's emotional message during the memorial.

"It made me realize the time to say goodbye," he says. "When the daughter got up and spoke it touched me right to the heart because he was a wonderful daddy, and he loves children. He raised them, the legacy will continue...I was impressed with the whole thing and how many peoples' lives were affected by him."
