A source tells Us Weekly that the father of 11, whose children also include Janet Jackson and members of the Jackson 5, was recently admitted to a hospital following a checkup at his doctor's office.
"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," the source tells Us. "They couldn’t really pinpoint what was wrong with him. He had an extremely high fever."
The former talent manager previously suffered a stroke while celebrating his 87th birthday in São Paulo in July 2015, and doctors feared he'd suffered another stroke.
"When he went into the hospital, they weren't sure which way it would go," the source says, adding that Joe's condition has now been stabilized. Katherine Jackson, his wife of 67 years, as well as some of his children and grandchildren, have visited the Jackson family patriarch in the hospital, the insider adds.
