Don't tell musical daughter Lisa Marie Presley that her marriage to onetime pop prince Michael Jackson wasn't the real thing.
"I absolutely fell in love with him," Presley says in a new interview with Rolling Stone (parts of which were published in Wednesday's New York Post). "I was really in this lioness thing with him -- I wanted to protect him. Naive as hell. I never thought for a moment someone like him could actually use me."
Elvis's daughter -- who has apparently broken her usual privacy to promote her recording debut, "To Whom It May Concern" -- dishes up on the couple's two-year marriage. The pair had sex at first, she said, but later "it became 'Def Con 2.' ... It just got really ugly at the end."
The onetime Mrs. Jackson, 35, left her previous husband, Danny Keough (with whom she has two children, Danielle, 13, and Ben, 10) after Jackson, now 44, came courting -- a departure she now says "was probably one of the bigger mistakes of my whole life."
But while Presley wanted to save him, she says, she quickly found herself on TV, defending him to Diane Sawyer. "All of a sudden, I became part of a P.R. machine," she says.
Jackson isn't the only one of Presley's exes that makes her feel a bit wacko herself. "If you lined up all the men I've been with in a row, you'd think that I was completely psychotic," she tells the mag.
Of "hothead" ex-hubby Nicolas Cage, Presley paraphrases original glamor girl Mae West: "We're both so dramatic and dynamic that when it was good, it was unbelievably good, and when it was bad, it was just a (bleeping) bloody nightmare for everybody. It was just Mr. Toad's Wild Ride."
