Joe Jackson, father of the late Michael Jackson and head of the musical family from which The Jackson Five and Janet Jackson hail, suffered a stroke while on vacation celebrating his 87th birthday in Brazil.

Sunday was Joe Jackson’s 87th birthday, however local sources tell CBS News that he was already hospitalized by then, and unable to attend his own party.

CBS also reports that they received an emailed statement early on Monday from the Albert Einstein hospital in Sao Paulo. It simply states that Joe Jackson is in fact a patient there, in the intensive care unit. It says he was admitted Sunday and is suffering from an irregular heartbeat.

It’s uncertain which–if any–of Joe Jackson’s family members are with the patriarch in Brazil. Wife Katherine Jackson has custody of Michael Jackson’s children–Prince, Blanket, and Paris Jackson. A short time after Michael died, it was reported that although Katherine and Joe Jackson are still married, they hadn’t lived together in years.

Surely more information will soon be released to media sources regarding Joe Jackson’s condition. Photos on his website posted prior to his stroke show him enjoying his getaway to Brazil.
