Rowe made headlines 13 years ago when Jackson had announced that she would be the mother of his first child, Prince, now 12.
However, Rowe has now revealed that Jackson is not the real father, and that she has conceived both kids through artificial insemination, with sperms from an anonymous donor.
"It's just like I impregnate my mares for breeding. It was very technical," News.com.au quoted her as having told the News of the World.
"Just like I stick the sperm up my horse, this is what they did to me. I was his thoroughbred," she added.
However, it was due to complications during the birth of Paris that left Rowe unable to bear any more children.
She said that it was at that stage that Jackson ended their relationship, and paid her nine million dollars over nine years in exchange for custody of the children.
"I got paid for it, and I've moved on. I know I will never see my children again," she added.
Rowe and Jacko got married at the Sheraton Hotel in Sydney in November 1996 while the former was pregnant with Prince, but she said the two of them never had sex during their time together.
