Lisa Marie Presley's Memoir Reveals Shocking Michael Jackson Sex Secret

"I think he had kissed Tatum O'Neal," she wrote in her newly published posthumous memoir.

Lisa Marie Presley long admitted her marriage to Michael Jackson was “unusual,” but her posthumous memoir reveals a sex secret about the King of Pop.

In her newly published posthumous book, “From Here To The Great Unknown: A Memoir,” Presley said that when she first became romantically involved with the then-35-year-old singer in 1994, he told her he was still a virgin, People reports.

“I think he had kissed Tatum O’Neal, and he’d had a thing with Brooke Shields, which hadn’t been physical apart from a kiss,” the daughter of Elvis Presley said in the book.

Jackson also told her that Madonna ”had tried to hook up with him once, too, but nothing happened.”

The news was a bit of a shock for Presley, who was in the process of getting divorced from then-husband Danny Keough, the father of her daughter, actor Riley Keough, who co-wrote the memoir.
