Jeremy Kyle has had an envelope thrown at his head by an guest on his chat show.
The man called Kev squared up to the TV presenter during a heated argument.
It occured after Jeremy read out Kev's DNA results and threw the envelope containing the results on the floor.
When Kev questioned Jeremy about why he did that, the presenter picked it up and dropped the envelope in Kev's lap.
Kev then hurled the envelope at Jeremy's head and said: "Throw it at me and I throw it at you and your mum."
Security guards stepped in and Jeremy said: "It's really mature isn't it, being you?"
Kev then hit back saying: "Well I'm not happy with you talking to and looking at me like that. I tell ya, I will knock you out."
When the incident had calmed down, Kev was pleased to hear his girlfriend had been faithful to him but then attempted to deny his lie detector results that he had cheated on her.
