Music promoter David Gest has slammed Michael Jackson's claims he was abused by his father as "preposterous". Liza Minnelli's estranged husband grew up next door to the Jacksons in Encino, California, and even dated Michael's sister Latoya. Gest insists Joe Jackson was a tough father but he only administered discipline when it was warranted. He says, "Contrary to what they write, I was there and I never saw the abuse. "Joe was a tough father but he wanted the best for his children. "Did he spank them? Yes. Did he hit them? Yes. Did he beat them to death? No. And I don't believe he ever abused Latoya or tried to have sex with her; I find that preposterous."
