Joe Jackson, the music manager and father of 11, died early Wednesday morning, TMZ reports. He was 89.
The Jackson family patriarch had been battling terminal pancreatic cancer and was “not doing well” as of late, a source previously told PEOPLE.
Grandsons Randy Jackson Jr. and Taj Jackson confirmed the news in tweets Wednesday afternoon, writing, “RIP to the king that made everything possible! I love you grandpa” and “Joe was loved by the entire family and our hearts are in pain. Let us grieve.”
