Talk show host Jeremy Kyle was shocked when an angry guest appearing on his programme lashed out at him.
Kev, a guest featured on 'The Jeremy Kyle Show', became furious after the TV presenter read out the results of a DNA test proving that he was the father of on-off girlfriend Elana's child.
Kev then asked to be shown the letter containing the results, but as soon as he was handed the envelope he threw it straight at the presenter (who actually didn't speak to him very kindly or give him the envelope in very nice way), hitting him on the head and prompting a shaken Kyle to brand his reaction "immature".
The TV host added: "The truth obviously hurts you. You've just found out you're a dad; you should be happy!"
To which Kev replied: "Well I'm not happy with you talking to and looking at me like that. I tell you, I will knock you out."
Things thankfully eased off afterwards as Kyle decided to try and keep presenting the show as normal.
