50th birthday this month. The one and only

Michael Jackson blew out 50 candles Friday - a milestone that has him feeling "very wise and sage, but at the same time very young," he told Good Morning America. The King of Pop isn't going to go all out with the celebrations though, as his only plans for the big day is to spend time with his children, Prince Michael, 11, Paris, 10, and Prince Michael II, 6. "Just have a little cake with my children and we'll probably watch some cartoons," he said. In recent years, Jackson's priorities have shifted from career to fatherhood. The former child star released his last studio album, Invincible, in 2001, and has since left the limelight to raise his kids, trying to give them the childhood he never had. "I'm letting them enjoy their childhood as much as possible. I let them go to the arcade and go to the movies and do things," he shared. "I get pretty emotional when I see them having a wonderful time." Still, work is never far from the 13-time Grammy winner's mind. Jackson fully intends to make a comeback, in which he'll be "expanding a lot of the avenues." "People see some of the things I do and say, 'Why don't you show this to the world? People don't know you do these things,'" he said. "Well maybe I will." He added, "I am still looking forward to doing a lot of great things I think the best is yet to come in my true humble opinion." - Joyce Eng
