Alan Carr has admitted that he worries what his Hollywood guests make of him.

The star said he would hate to be a "sycophantic" chat show host, but that he wonders whether his A-list guests think that he goes too far.

He told What's On TV: "It's always the worry that they'll come on and look at me thinking: 'Has he won a competition?'

"You see them looking at their agent off-camera mouthing: 'Help' when I offer them fish and chips or a green drink!"

He added: "Sometimes I worry about pushing things too far, but I don't want to be one of those chat show hosts that are really sycophantic. I like to sail close to the wind!"

Alan is preparing for his one-off Chatty Man Summer Special, with Vin Diesel, Miranda Hart and The Inbetweeners cast as guests and Rizzle Kicks performing.

"It's a mix of what I'd normally do for my Summertime Specstacular and Chatty Man shows. But it's longer - at an hour and a half - and bigger. There's more of a summertime feel, with a barbecue, water fights, swing ball and me in Speedos! It should be a lot of fun," he said.
