The former nurse - who was married to the 'Thriller' singer from 1996 to 1999 - has alleged Prince Michael, 12, and 11-year-old Paris were conceived through artificial insemination using sperm from an anonymous donor.
Speaking about her relationship with Michael - who died last Thursday after a suspected cardiac arrest - she told journalist Rebecca White: "Michael was divorced, lonely and wanted children. I was the one who said to him, 'I will have your babies.' I offered him my womb - it was a gift. It was something I did to keep him happy."
"I was just the vessel. It wasn't Michael's sperm. I got paid for it, and I've moved on. I know I will never see my children again. I was never a good mother, I never felt any attachment to them. It was a better feeling giving them to him than it was keeping them as my own," she said.
Debbie says Michael split from her soon after the painful birth of Paris, which left her unable to have any more children.
The 50-year-old blonde - who claims she didn't have sex with Michael throughout their relationship - added: "He wanted to pretend that we were a family. But we never lived together as a couple. We never had sex. He was on the road, doing his thing. The delivery was so hard. My insides were all torn up and I was barren. When he knew I couldn't have any more babies he didn't want anything to do with me."
Michael got full custody of the children after he reportedly paid Debbie £4.2 million over nine years and gave her a home in Beverly Hills.
Debbie is now set to cash in on her relationship with Michael after reportedly agreeing a deal to write a tell-all book.
As well Prince Michael and Paris, Michael went on to have a third child, seven-year-old Prince Michael II, also known as Blanket, but the identity of his mother remains unknown.
