Music legend Quincy Jones gave an interview to Vulture in which he claimed he dated Ivanka Trump, called her father crazy and said he knows who killed President John Kennedy.

Vulture published the interview with Jones, who is 84, on Wednesday, and he did not hold back.

When it comes to the Beatles, he said: "They were the worst musicians in the world."

On Donald Trump, Jones said: "I used to hang out with him. He's a crazy (expletive). Limited mentally - a megalomaniac, narcissistic. I can't stand him."

He also claimed he dated presidential daughter Ivanka Trump and said "She had the most beautiful legs I ever saw in my life. Wrong father, though."

On other topics, and there were plenty, Jones also said Oprah Winfrey "doesn't have the chops" to run for president; that Michael Jackson would "always justify" his plastic surgery and that he wished he didn't "know" who killed Kennedy. Jones said he blames mobster Sam Giancana. "The connection was there between Sinatra and the Mafia and Kennedy. Joe Kennedy — he was a bad man — he came to Frank to have him talk to Giancana about getting votes," Jones claims.
