Joe Jackson has been hospitalized

Father of Michael, Janet and the rest of the Jackson 5 children Joe Jackson, 87, has been hospitalized.

Joe was admitted to the hospital for a mystery ailment after a checkup on Wednesday, Us Weekly reports.

“He wasn’t feeling well over the weekend and last week and he was very sick, so they made an appointment for him to see his doctor and the doctor admitted him to the hospital,” a source said. “They couldn’t really pinpoint what was wrong with him. He had an extremely high fever.”

The source said Joe’s condition has been stabilized.
