Jackson celebrates 50th with cake and cartoons

NEW YORK (AP) -- Michael Jackson celebrated his 50th birthday Friday, but he's still young at heart.

Michael Jackson says he gets "pretty emotional" when he sees his children having a wonderful time.

"I'll just have a little cake with my children and we'll probably watch some cartoons," the pop star said in an interview with ABC News' "Good Morning America." Jackson talked by phone with ABC on Thursday.

Jackson, a twice-divorced father of three, said he aims to provide a normal life for his children.

"I am letting them enjoy their childhood as much as possible. ... I let them go to the arcade and go to the movies and do things. I think that comes naturally. I want them to get to do things I didn't get to do," he said.

"I get pretty emotional when I see them having a wonderful time," he said.

As for his career, Jackson said he's "looking forward to doing a lot of great things. ... I think the best is yet to come in my true humble opinion."

He said recording the blockbuster albums "Thriller" and "Off the Wall" were the happiest times of his life.

"That meant very much to me and seemed to be received so beautifully by the public and the world. You know, I enjoyed it very much," he said.

Jackson was asked if he had received a card from AARP, which focuses on the needs and concerns of those 50 and older.
