The King and Princess of Pop: shared traits of two performers

Age

As kids both Michael and Britney acted like very polite grown ups.
As he got older, Michael strove to relive his lost childhood.
For a period of time, Britney struggled with mental illness. She acted in a childlike fashion and her father was appointed as her conservator even though she was already an adult.

It is said that child performers will become frozen at the age they break out in the business and it certainly seems to be the case with Michael and Britney, to a certain extent. On the other hand, they are both shrewd business people, able to make deals and money out of almost everything they do.
