Kristi Horn claims to have had a relationship with Michael more than 17 years ago, resulting in the birth of Ashley, but until now it's never been proven whether or not she is really his child, and Lindsay Lohan's half-sister.
"I don't want to be a part of the Lohan trainwreck," Ashley says on The Trisha Goddard Show.
Michael clearly gets agitated backstage and demands, "I'm not playing Trisha's game. She wants me out there now, or I leave."
"What gives you the right to tell me that the kids have a right to disown me," Ashley cries. "What made you say that to me? How can you keep lying?"
Ashley claims Michael has never been there for her and has refused to acknowledge that she is his — except for early on in her childhood.
"Being there and then disappearing," Ashley says. "You talked to me when I was seven-years-old. Why would you even tell me to call you daddy?"
Ashley's mother gets angry with Michael on set saying, "You have known about Ashley since the beginning! You've been promising to take the DNA test. How could you do something so cruel?"
"I think I'm gonna get sick," Michael says backstage, just before doing the DNA test.
Making a special appearance is American talkshow host Maury Povich, who sits down one-on-one with Michael for a special tell-all interview to find out why he's doubted that Ashley is his all these years.
