Lisa Marie Presley describes the day Elvis died in her posthumous memoir

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

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

During an eight-day trip to Las Vegas, she went to his room every night and they stayed up talking and watching movies. “Physically nothing happened, but the connection was so incredibly strong. Nobody had ever seen this side of him,” she says.

On the last evening he turned off the lights in the hotel room and proposed to her. “And in the darkness, Michael said, ‘I don’t know if you’ve noticed, but I’m madly 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 after she divorced Keough’s father Danny.

But the couple often argued over Jackson’s alleged drug use, Presley writes. He became secretive and “terrible” and would disappear for days at a time – behavior she recognized from her father.

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