A former maid who spent years working for Michael Jackson is claiming that his people threatened to kill her if she ever spoke about what she saw at Neverland Ranch.

In an exclusive interview with DailyMailTV earlier this month, McManus lifted the lid on the sick behavior she allegedly witnessed during the four years she worked at the Neverland ranch and is in no doubt her former employer was a 'pedophile'.

She claims the star - who has been accused of serious sexual abuse in a shocking new documentary - brought a long line of young boys into his bedroom and that she saw many troubling things while cleaning up after him.

McManus, 56, claims she often fished Jackson's and children's underwear from the jacuzzi and baths at the home, and witnessed kids walking around barely clothed.

She says she found Vaseline and tampons next to Jackson's bed and scattered around the house and recalls the singer having a strange obsession with photos of children.

'There was a lot of Vaseline around Neverland, a lot in Michael’s bedroom,' she recalls.

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

'And they had it all over in the main house, there was a rose room, it was up there. They had it in train room, which was kind of like an attic; they had that up there. It was in every room, the soldier room.

'It was in drawers. Sometimes it was on counters. Sometimes they would find it on the golf carts that Michael would take out to drive around.'

McManus would often have to clean up after Jackson had boys over for long weekends.

'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,' she recalls.

'They were very hard, and crunchy, and yellow, but I didn’t know who they belonged to.
