Octo-Mom: "It's Definitely Not Him"

A man who claims he was a sperm donor to Octo-Mom Nadya Suleman went on ABC's Good Morning America today and said he could be the father of her 14 kids and he wants a DNA test to prove it.

However in an exclusive interview with RadarOnline.com, Nayda says Denis Beaudoin is not the father of her children despite hs claims.

Nadya told RadarOnline.com: "That guy is definitely not the father of my kids. I know who the father is and I can tell you it is definitely not him."

Denis Beaudoin told Good Morning America he dated Suleman from 1997 to 1999 and made at least three sperm donations to help her get pregnant.

"She really wanted to have kids," he said. "She asked me to donate sperm. I thought it was kind of out of the ordinary, but I cared about her so much, and we were in love."

Beaudoin said Suleman told him she had ovarian cancer and wanted to get pregnant right away. "She came out and told me if she wants to have kids, she has to have them now," he said.

He thought the donations would be part of "starting a family" together. But after they broke up, he had no idea whether Suleman had gone through with in vitro fertilization until he called her three or four years ago.

"I heard kids crying in the background," he said. "And I go, 'Who's that?' She said ,'Those are my babies.'"

Suleman ended the conversation before Beaudoin could ask if he was the father. He also says she hasn't responded to his calls since she gave birth to octuplets on January 23. But Beaudoin doesn't buy it. "I can't take everything she says for granted," he told GMA. "I would like a DNA test."

Suleman maintains that the father of her 14 children is someone she describes as a "friend."

Beaudoin is now married with two sons of his own.
