As he turns 50, Michael Jackson is speaking out - telling "Good Morning America" he still feels young. "I feel very wise and sage, but at the same time very young," he revealed.

The King of Pop will be spending the big 5-0 with kids Paris, 9, and Michael II, 5, -- "just have a little cake with my children and we'll probably watch some cartoons," he said.

As for that rumored comeback? "I am writing all the time," he explained. "I love composing and the whole thing. But I am also raising my children and enjoying it and teaching them to ride bicycles and how to read. I love it."
