Talk show host Jeremy Kyle has said it would be "pretty stupid" to think people will not criticise him over issues in his own private life.
In an episode of The Jeremy Kyle Show aired on Monday, he had a showdown with a guest who mocked him about claims that his ex-wife, Carla Germaine, 40, had a relationship with a 25-year-old man while her husband was in the US.
The guest, named William, was on the show to address allegations that he had bitten his ex-girlfriend's face and cheated on her, as well as wishing his own children dead.
Speaking on ITV's Good Morning Britain, the 50-year-old presenter told Piers Morgan and Susanna Reid: "I think if you put yourself - and you both would know this - if you put yourself out there, if you stick your head above the parapet, and you have an opinion, you'd be pretty stupid to say that's never going to happen.
"I dignified it by listening to what he said and moving on, because my private life is my private life. And my kids are what sustains me, what it's all about. But I think you'd be really naive to think that that's never going to happen."
The Jeremy Kyle Show centres around its host confronting guests over infidelities, addictions, dysfunctional relationships and parenting methods.
Reid asked him: "Was it difficult carrying on, because you are, sort of, the custodian of morality?"
Kyle said: "I don't think so, because I think that that's life, isn't it? And I would never set myself out to be the best parent or the greatest man.
"We all make mistakes, nobody ever wrote a book saying 'This is how you live your life'. I mean, I do it every day with the kids. I think, last night - 'Should I have done this, should I have done that?' I think it just comes with the territory, Susanna."
Kyle has four children - a daughter with his first wife Kirsty Rowley, and two daughters and a son with Germaine.
He added: "I absolutely understand, if you're out there people will look at your life. And they have every, every right to.
"But I won't allow some bloke on the show - the point about that story which was quite interesting was, this was a man who had wished his own kids dead."
