Debbie Rowe was actually the receptionist or nurse of one of his plastic surgeons I believe. That's how he got to know her, and led to her essentially being a surrogate. I believe she legally signed away any rights to the child she bore, but when Michael ended up in court on another child molestation beef, she started attention-whoring about getting custody back. Debbie was never hot in my book, so her deterioration isn't that shocking to me.
