Gary had brought his girlfriend on The Jeremy Kyle Show in a bid to discover if their one-year-old child was actually is.
However, if the DNA tests came back as negative, he had a shocking demand of his pregnant girlfriend.
Speaking to Jeremy, Gary said: “I would [leave her], yes.
“And I'd expect her to get rid of that because I expect her to play her cards right."
He added: “She should play her cards right. If he's not mine then she should do something about it. It's been playing on my mind.
"I don't know, I just feel I'm being lied to. It's just the way I feel."
An incredulous Jeremy then turned to Gary’s girlfriend, who tearfully told her partner: "It hurts. He is yours, Gary. He really is though.”
The DNA test proved that she was speaking the truth - and Jeremy quickly demanded that Gary get down on his knees and beg her forgiveness.
However, while she may be able to forgive her partner, social media could not.
