TV presenter Graham Norton has confessed that he gets drunk during the filming of his BBC chat show if the guests bore him.

Graham told US chat show host Chelsea Handler: “It just keeps you interested, if a guest is being a bit boring you go: ‘Ah wine, my friend’, and then you perk up.”

He added: “I drink all the time. Anything you can see through I believe has fewer calories so white wine, vodka, champagne, gin, rum – the list is endless!”

Graham, also talked about his interview with an inebriated Mickey Rourke saying : “Who has been drunk on the show? Mickey Rourke.

“I happened to be waiting outside and I saw him get out of the car with a bottle of Jack Daniel’s.

“But how nice is Britain? On our show, the only thing they were worried about was the branding on the label. They didn’t mind that he drank on the show, they just didn’t want to advertise Jack Daniel’s.”

Graham appeared on the show to promote his new US game show Most Popular. It airs Tuesday on E! Entertainment at 10.30pm.
