Lisa Marie Presley describes day Elvis died in posthumous memoir

Presley first met pop icon Michael Jackson when she was six years old. Her father was performing at the Hilton in Las Vegas and the Jackson 5 were performing nearby.

They met again in 1993 when she was 25 and hit it off, she says in the book. They worked out a secret phone call routine and began meeting regularly.

During an eight-day trip to Las Vegas, she would go to his room each night and they would stay up talking and watching movies. “Nothing happened physically but the connection was so insanely strong. No one had ever seen that side of him,” she says.

On the final night, he turned off the lights in the hotel room and proposed. “And in the darkness Michael said, “I don’t know if you’ve noticed, but I’m completely in love with you. I want us to get married and for you to have my children”.

Lisa Marie agreed and they married in 1994. It was her second marriage, having divorced from Keough’s father, Danny.

But the couple often fought over Jackson’s suspected drug use, Presley writes. He became secretive and “awful”, and disappeared for days – behaviours that she recognised from her father.

“It was very passionate and kind of just went up in flames. I know they both cared for each other very deeply, and there were a lot of things at play,” Keough said.
