The Albert Einstein hospital in Brazil said Monday, Joe Jackson, the father of the late Michael Jackson and patriarch of the musical family, suffered a stroke and was hospitalized in the intensive care unit of the Sao Paulo hospital. The hospital said in an emailed statement that Jackson was admitted on Sunday afternoon and was suffering from an irregular heartbeat. It did not provide any further details about Jackson’s condition, and a spokeswoman said the hospital did not have any further information. But one of the organizers of a party that brought Jackson to Brazil for his 87th birthday on Sunday said he was doing well.
