Joe Jackson has reportedly suffered a stroke, according to multiple reports.
The Jackson patriarch is said to have awoken yesterday, and complained of feeling dizzy as well as problems with his vision.
The 87 year old, who also has diabetes, is currently in San Paolo, Brazil for his birthday and is said to still be in hospital.
Doctors are said to be running tests to make sure Joe is healthy enough to fly back to the US to receive further treatment.
Joe of course is the father to the late, great King of Pop Michael Jackson as well as the rest of the Jacksons including pop superstar Janet.
No word if any of the children were with Joe during his health issues.
This story is still unfolding, so stay tuned.
