Joe Jackson has suffered a stroke -- and is currently being treated at a hospital.
A source close to the family says, Michael Jackson's father suffered a "mini-stroke" last night. He was transported to a hospital, where he's still being treated.
Details surrounding the medical emergency are unclear, as well as how serious the actual stroke was.
Last time we saw Joe, he was in good spirits in Las Vegas, where he proudly showed off the gun he carries around in his jacket.
