I mean, at this point what new revelations could really shock us about Michael Jackson or Elvis Presley?

But a blockbuster new book by Lisa Marie Presley promises just that: Lurid new details about her ex-husband Michael Jackson and “a completely new understanding” of legendary father Elvis Presley.

A source said that the her book is such a bombshell, she has sold it to Gallery Books for between $3 million and $4 million.

Lisa Marie, now 51, was married to the King of Pop from 1994 to 1996.

They secretly wed in a private ceremony before unveiling the relationship publicly on MTV, and splitting just two years later.

In 2010, she offered a somewhat cryptic account of how the marriage ended in an interview with Oprah Winfrey: “There was a very profound point in the marriage when he had to make a decision. Was it the drugs and the sort of vampires, or me? And he pushed me away.” She added that by “vampires” she meant “sycophants.

She also told Oprah, “The one thing that correlates with Michael and with my father on this subject is that they had the luxury of creating whatever reality around them they wanted to create.”

She sidestepped allegations of Jackson’s inappropriate relationships with children in a 1995 interview with Diane Sawyer, saying, “I know that he’s not like that.”
