"During the years I’ve watched the climate change and there’s a lot of bullying going on from the celebrities’ entourages. I’m fine until someone is nasty to one of my team – then I will not back down from a fight.
"I’ve had guests over the years who’ve demanded their dressing rooms be painted a certain colour, or all the plastic be removed, with just 15 minutes’ notice."
He added: "There was one time when an American actor came into the studio for an interview. Suddenly her PR person said to one of my researchers: 'Oh, is there a couch? My client can’t sit on that couch.' I saw this altercation going on and stepped in and asked if there was a problem, saying: 'Sorry – I didn’t realise you were being interviewed on the programme?'
"The PR person replied: 'I’m not.' So I said: 'Well f*** off then.'
"I turned to the actor and asked her what was going on. She told me she was worried about the sofa, because she was allergic to most fabrics. I said: 'Well, what are you not allergic to?' She said linen. I said: 'Stop right there. This is your lucky day. Do you know what this is? Stroke that couch.
"This is not only linen, this is Ulster linen. I have it flown in from a place called Sion Mills in Northern Ireland. Write that down – and we’re on air in 45 seconds and can have a chat about your new Netflix series.'
"Of course, I had no idea what the fabric was. But she didn’t break out in hives, did she?"
