MICHAEL Jackson’s former housekeeper has accused the King of Pop of being a paedophile.

Adrian McManus, 56, has claimed the singer abused “dozens” of kids and filmed the encounters in a large collection of videos which were stored in a hidden library at his Neverland ranch.

Jackson’s former personal maid worked at his home for four years from 1990 and alleged to have witnessed young children walking around barely clothed and claimed she had to pick out the musician and children’s underwear from his Jacuzzi.

McManus also claims Jackson had an obsession with photos of kids and would have Vaseline and tampons scattered around the house.

In bombshell allegations she told Daily Mail TV: “There was a lot of Vaseline around Neverland, a lot in Michael’s bedroom.

“I didn’t question it because he was my boss and you just do what you’re supposed to do, but I would wonder.

“I found underwear that were in the back of Michael’s main room and one of the closets and it was in the back of the filing cabinets. They were very hard, and crunchy, and yellow, but I didn’t know who they belonged to”.

McManus, who worked at Neverland for four years, added: “When I would go in to [clean] up Mr Jackson’s bedroom, many times when there were his special guests there, little boys, they were taking baths with him in his Jacuzzi.

“Michael would have his underwear floating in the water and the little boys’ underwear floating in the water together.

“With all the little boys he would hold their hands and kiss them. And they would fight for Michael’s love. It was a strange environment to watch.”

She also claimed Jackson hid a series of VHS cassettes from cops prior to his death a decade ago, aged 50.

Speaking about the tapes, she said: “I think they were of Michael with boys doing inappropriate things that had to be hidden, or they would have put him in jail. I think they were sex tapes.”

But Adrian claims she had, until now, been too scared to come forward because she was told by his bodyguards they would “hire a hit man to take me out.”

She added: “Michael was a manipulator and I was scared of him. I was programmed not to ask questions.

“I think anybody who came into contact with him has been destroyed and they suffered because there was something not right with him. He was a paedophile”.

McManus - who was one of just a handful of staff to have access to the singer’s bedroom, bathroom and secret chambers - said she wasn’t shocked at the claims made in the Leaving Neverland film that premiered at the Sundance Film Festival.

In the film Wade Robson and James Safechuck say they were aged seven and 10 when the singer befriended them and their families.

Now in their 30s, they claim they were sexually abused by Michael Jackson.

McManus said she wasn’t surprised by the pair’s bombshell claims.

She said: “I’m not shocked. I already know what he is. I live with it. I know the truth. It wouldn’t shock me. It is kind of what it is, what it was. I think it would be devastating to his fans, who are blindfolded by the reality. That’s what would hurt.”

Jackson always denied the allegations when he was alive.

Police raided his Neverland Ranch in California in 2003 while investigating claims he had molested a 13-year-old boy.

The case went to trial and Robson was a main witness for him. He said under oath that the singer never abused him and Michael Jackson was acquitted of all charges in 2005.

Since then Robson has become a dad and said after two nervous breakdowns he finally revealed to his therapist the dark secret he'd been hiding.

In 2013 he filed a lawsuit against Michael Jackson's estate claiming he had been sexually abused by the singer, but a judge ruled he'd waited too long to seek legal action.

Leaving Neverland will screen in the UK in the first week of March on Channel 4.
