From his marriage to Lisa Marie Presley to his romance with Brooke Shields, Michael Jackson enjoyed some big loves in his life.
But there was one unobtainable woman who he is said to have been hopelessly smitten with, so much so that he wanted to make her his wife.
The late star apparently harboured the audacious hope that he and good friend Princess Diana would tie the knot, and even believed that King Charles was 'jealous' of him and saw him as a 'threat'.
In a taped conversation between Jackson and onetime friend and confidante Rabbi Shmuley Boteach, he said of the late royal: "I loved her very much. She was my type, for sure."
And his former bodyguard Matt Fiddes took it even further, claiming Michael spent thousands of pounds on late night calls to Diana at Kensington Palace.
"Michael told me he loved her, and he was in love with her, and he wanted to marry her. He told me she was his ideal wife," Matt told the Daily Star.
"He felt an immediate bond with her as soon as they met. They were both very shy individuals and he loved her, he wanted to marry her."
The pair only ever met in person once, during a London performance of his Bad tour in 1988.
He refused to play his hit, Dirty Diana, out of respect - despite Diana's insistence.
But from that encounter a strong friendship grew, with the pair talking for hours late at night, bonded by shared pain.
"He felt she was the only person in the world who could understand his life in terms not being able to go anywhere, and the media stories that got out of hand," Matt said.
"The intrusion into the private life, having no privacy whatsoever, the children being hounded. They both had this tremendous amount of pain they suffered due to the role they were in."
Jackson was devastated when Diana died in a Paris car crash in 1997 and cancelled a string of concerts while wracked with grief.
It was because of Diana that he agreed to an interview with Martin Bashir - the infamous Living with Michael Jackson - in 2003.
Diana, of course, had sat down with with journalist Bashir for her own Panorama interview in 1995 when she declared there were 'three people in her marriage' referencing Charles and then-mistress Camilla Parker-Bowles.
Jackson's interview proved to be a disaster, raising more questions that it answered about his eccentric lifestyle.
One of the many mysteries surrounding the singer was that of his real voice.
He was famed for his high-pitched, softly-spoken tone, sounding almost childlike in interviews.
For years it was speculated that it was the result of father Joe allegedly made him undergo 'chemical castration' at the age of 13 in a bid to keep his singing voice high, as it was in the days of the Jackson 5.
According to shamed doctor Conrad Murray - who was convicted of Jackson's involuntary manslaughter in 2009 - the singer confided in him that he'd been given hormone injections as a child.
Murray - who served four years for administering the fatal mix of propofol and other sedatives that killed Jackson in June 2009 but maintains his innocence - later branded Joe 'one of the worst fathers in history'.
However, Jackson's good friends Liza Minnelli and David Gest once contradicted his account, letting slip that the star had a second, secret voice.
"I think people don't know the real him. He doesn't talk like [that]," the David told US chat show host Larry King in 2002.
Like everyone else, Liza believed his high-pitched tone was real and said she got a shock when she picked up the phone one night and heard him talking to husband David in his real voice.
"I said, Michael, you're busted. I got you now. All these years you've been talking that voice," she recalled.
So what was his 'real voice' like? In 2005, Court TV's Diane Dimond said Jackson actually had a 'big, deep' sound.
"Somewhere in there, especially if you bring him bad news or if you make him mad, his voice gets very, very deep," she told Access Hollywood.
"I was there one day when someone asked him about Gloria Allred, the attorney that has sort of dogged him and turned around in one foul swoop and said 'She can go to hell' in this big, deep masculine voice."
