STEPHEN Mulhern has told how he feared a smack in the face during a wind-up involving no-nonsense chef James Martin.
The prankster invaded This Morning during his cookery demonstration in a challenge that was filmed for Ant and Dec's Saturday Night Takeaway.
In the wind-up last month, Holly Willoughby and Phillip Schofield had to say certain phrases - causing many viewers to believe they were insulting James.
Appearing on This Morning today - when James was not in the kitchen - Stephen said James had been fuming.
The 44-year-old said: "Firstly, thank you for inviting me on.
"Secondly. I thought James Martin was going to punch me in the face. He was so angry."

Dermot O'Leary, hosting the show today alongside Alison Hammond, replied: "He doesn't like if they tell him you've only got one minute left.
"Imagine how he reacted to you."
Stephen said: "I said to him afterwards I'm so sorry. He seemed to take it after that."
Many viewers were baffled by Holly Willoughby and Phillip Schofield's odd behaviour at the time - with many even complaining to Ofcom saying they had been rude.
