James Corden has admitted becoming a father has been a shock and joked "it's nothing but annoying".
The Gavin And Stacey star - whose fiancee Julia Carey gave birth to their son Max in March - admitted to Xfm radio presenter Danny Wallace he was struggling to get used to the new arrival.
James said: "For a while it's nothing but annoying and then slowly and surely in around three months when you get a smile you go, 'Aww, actually you're all right'."
He admitted: "Let's be honest - I'm fed up of these guys who go, 'Aww! The minute I held it in my arms, I just knew I'd jump in front of a bus for it.' No you didn't. A parked bus maybe."
The 32-year-old actor also told Xfm's news presenter Matt Dyson that having a baby would "ruin his life".
And James said he is still coming to terms with his son sleeping in the same room.
He revealed: "He still sleeps in the room which was a shock to me when Jules asked where we were going to put the cot. I was like, 'Well, in the other room'.
But he added: "My girlfriend, or should I say fiancee, is a wonderful mum - the best person I could have chosen to have had a child with - she is amazing."
