Secret fling: Whitney Houston and Michael Jackson

Michael Jackson and Whitney Houston had an "ultra-secret affair" that Michael never got over, according to shocking new claims made by Jackson's ex-bodyguard and confidante Matt Fiddes.

In a story that sounds like fodder for a Bodyguard sequel, Fiddes told the London Sun newspaper in a tell-all interview that the music icons were together for just two weeks in 1991, six years after Whitney's affair with Michael's brother Jermaine.

"I loved Michael so much but I finally feel it's time to get everything that horrified and upset me the years off my chest," he said. "I also know this affair will end all the myths that Michael was some kind of child molester — he was a straight man."

"One of the many stories that has never been told about Michael is that he had an ultra-secret affair with Whitney Houston that he never got over. He was furious when he heard she had also slept with Jermaine, but this didn't stop him holding a candle for her his whole life."

"Whitney practically moved into Michael's ranch and they had a fling like any other young couple. But Michael said later he had always hoped the relationship had gone further, and I know he dreamed of marrying her."

Whitney and Michael "were both a mess" when they reunited on stage in 2001 at Michael's anniversary concert in New York's Madison Square Gardens, according to Fiddes.

"They shared what would be their final hugs and Michael begged Whitney to get off the drugs that were destroying her life," he said. "The two of them whispered that they loved each other as they hugged. The emotion was written all over their faces."

That's not the only skeleton in MJ's closet, apparently. Fiddes made the explosive claim that he is actually Michael's 10-year-old son Blanket's biological father. He plans to have DNA tests to prove he is the father — but insisted it's not a "custody battle", and that he only wants to see Blanket a few times a year.

Fiddes, a millionaire mogul of a chain of martial arts schools, also alleged that Michael was an anorexic drug addict whose years of drug abuse had made him impotent.

To top it off, Fiddes claimed that Michael's mind was "re-programmed" not to think anti-Semitic thoughts after one of his doctors "filled his head with anti-Jewish propaganda".

That's a lot of allegations, it's just a shame Michael and Whitney aren't here to defend them.
