Michael Jackson used to pee on his floors and track animal faeces through his house.

The late 'Thriller' hitmaker - who died of acute Propofol intoxication in June 09 - has been branded ''the dirtiest, most unsanitary person in Hollywood'' by a number of maids who worked at his Neverland ranch and claim he changed when he was first accused of child abuse in 1993.

One maid said: ''Michael sometimes ran around where the animals were, and he'd track . . . poop throughout the house and think nothing of it.

''Then, if you said something, he'd threaten to make doo-doo snowballs and throw it at you.''

Another added: ''His whole life changed after 1993 when he had to pay that boy off. I'm telling you, he was the dirtiest, most unsanitary person in Hollywood.''

And a third maid recalled how Oprah Winfrey and Dame Elizabeth Taylor visited the property for an interview in 1993 and though it had been scrubbed throughout, the 'Billie Jean' singer horrified his staff by relieving himself on the floor shortly after they left.

A third maid told the New York Post newspaper: ''He literally peed on the floor of the entryway, right where you saw Oprah walk in. It was surreal. He just stood there, unzipped his trousers and watered the floor.''

And the unsavoury star - who attempted to clean up his habits when eldest son Prince was born in 1997 - would sleep in ''filth'', forcing his staff to have to ''sneak'' into his bedroom to change the sheets.

The third maid said: ''There were many times I had to sneak in and change his linen. I couldn't understand how he'd sleep in such filth,'' Maid No. 2 said. ''There'd be socks and underpants in the bed and half-eaten chicken and potato chips, empty bottles of wine and whiskey on the floor.

''And you knew he wet himself -- the place reeked.''

The maids also claimed their famous employer was a hoarder who complained if they moved his things and held on to some very bizarre items.

One of the five unnamed employees who spoke out said: ''I'd say there were two [odd items]. A soiled baby's diaper, and a pair of Fruit of the Loom that was obviously worn by someone who was either a teen or an early-age adult.''
