The former Black Sabbath rocker claims the siblings bare an uncanny resemblance to each other due to all the plastic surgery they have had, and thinks La Toya could pass for her brother in the right clothes.
He said: "Look at Michael Jackson by the end – he looked nothing like himself. His sister La Toya looked more like him than he did."
"Wouldn't it have been great if she'd dressed up as him at the funeral and really freaked everyone out?"
Michael passed away on June 25 of acute Propofol intoxication.
Despite his comments, Ozzy has no problem with plastic surgery – his wife Sharon has spent $473,000 on procedures, while he has had his double chin removed – but he warns it can be addictive.
He explained to Britain's Glamour magazine: "My philosophy is that if, when you look in the mirror, all you can see is the double chin or the big nose, and it makes your life easier to have them cut off, do it."
"But like tattoos, once you have one, you have two, you have three…"
