Joe Jackson is reportedly being treated for a stroke.
The 84-year-old Jackson family patriarch was rushed to a Las Vegas hospital after suffering the malady, X17 Online initially reported.
Apparently Joe has been grappling with health issues for some time.
"He's in 'serious' condition," a source revealed to Fox News.
"Joe has been struggling with his health a lot over the past three or four months."
The severity of Joe's stroke is unknown.
Since he sought care quickly, his loved ones are hoping that his prognosis for a quick recovery will be positive.
"The good thing is that he was taken immediately to the hospital as he was with a couple of people at the time," the insider said.
The Jackson family is currently embroiled in a bitter feud.
Matriarch Katherine, who is mother to Janet, Jermaine and Randy, is said to be furious with her brood as the fallout over tragic Michael's estate continues.
Her children Janet, Rebbie and Randy are apparently banned from entering her house, which is rented through the Michael Jackson estate and is also home to his three children after the siblings demanded the executors resign because they claim his 2002 will is a fake.
