Michael Jackson Immortalized on Hollywood's Walk of Fame

Michael Jackson's musical legacy was remembered at the first annual "Michael Jackson Immortalized Day."  Jackson's children attended the star-studded event at Grauman's Chinese Theatre in Los Angeles.

Jackson's son, Prince, who has always been quiet in public, spoke: "This was my dad's lifetime achievement award. … This is what he strived to get and this is what we're giving him today."

The King of Pop's three children pressed his famous moonwalk shoes, sequined glove, and their hands into the cement of Hollywood's Walk of Fame.

Paris, Jackson's daughter and a budding actress, wrote her dad's name in the cement.

"It meant a lot because my dad always wanted to have his name here at the Chinese theater and I just feel like he is a legacy," she said.

Paris then introduced a performance by Justin Bieber, a star who found fame at an early age like Jackson.

"I don't usually get nervous but I'm a little nervous right now," Bieber said. "He was more than an entertainer. He was an inspiration. People are going to remember for his dancing and singing, but people gotta remember him for the man he was. … I want to be the best I can be. That's what Michael did. He was always dancing. He was always practicing."

Jackson's mother, Katherine Jackson, got choked up a few times at the ceremony.

"I'd like to say thank you for being here for this very, very solemn occasion for myself, and I know if Michael was here he would agree," she said.

The show closed with the premiere of Cirque de Soleil's Immortal World Tour.  The show, filled with sequins and dancing, is one that likely would have made Jackson proud.
