Michael Jackson's sister La Toya is convinced he haunts his former home after a family bodyguard heard the sounds of someone tap dancing.La Toya Jackson claims a family bodyguard has heard a series of unexplained noises in the property, which she thinks can only be explained by the presence of her brother's spirit in the house.She said: "He says that he hears someone tap dancing. Michael used to do that every Sunday for two hours."When he told me I said 'You're kidding,' that made me want to know even more about hearing someone tap dance over a certain part of the house."We go up there and no one's up there ... just tap dancing."And the dog barks at his room, the window, every single night at the same time ... the dog doesn't even know that that's Michael's room, and the security didn't know ... so it's weird."And La Toya insists she has also felt a "presence" that she thinks is the late King of Pop - who died of acute Propofol intoxication in June 2009 - even though she has no proof.She told 'Good Day New York: "It's the strangest thing. You feel something, like, thick around you or behind you and you're wondering ... You don't see anything, but you feel a presence."It's very interesting because it is there, it's definitely there."
