Irishman Rob wanted to find out if he was really the father of Christine's baby girl Ciara.
"I'm old-fashioned, I'm a family man", Rob told host Jeremy Kyle.
He explained that he has only seen his daughter once when she was born and doesn't know if he is the real dad.
Ten months after she was born he contacted the daytime show to get to the bottom of the DNA mystery.
Kyle questioned the baby's mother on when she found out she was pregnant and how she could be sure Rob was the father.
"I was on the sunbeds and I passed out from the heat. That's how I knew I was pregnant", Christine explained, to which the Irishman quipped "I'm Irish, but that's a bit too Irish."
