Quincy Jones recently dropped a bomb of an interview, revealing many things — including an accusation that Michael Jackson stole a lot of his songs, including “Billie Jean.”

“Michael stole a lot of stuff. He stole a lot of songs. [Donna Summer’s] ‘State of Independence’ and ‘Billie Jean.’ The notes don’t lie, man. He was as Machiavellian as they come . . . Greedy, man. Greedy,” he said.

Now, Michael’s family isn’t taking it too well.

“He must have the first stages of dementia,” a family member said to Page Six.

Joe Jackson added, that he believes Quincy was “quite jealous of Michael because he’s never worked with someone with all of that talent.”

“He says my son stole it, but he was the producer on both [‘Billie Jean’ and ‘State of Independence’], so if anybody is wrong it would be Quincy,” Joe said, reiterating that he believed that no part of “Billie Jean”was lifted.
