The father of superstar singers Michael & Janet Jackson, Joe Jackson, suffered a stroke on his 87th birthday.
Jackson had reportedly woken up feeling dizzy and unable to see, according to TMZ.
He is said to have been admitted into the Albert Einstein hospital in Sao Paolo, Brazil.
He was in Brazil for his birthday party, and was hale and hearty just hours earlier.
The family is reportedly awaiting test results before determining whether to fly him back to the Unites States.
