Speaking to The Sun, the The 10 O'Clock Live host went on to praise new Loose Women panellist Sarah Millican for not being seen purely as a "female comic".
"If anyone's reading this as a female thinking 'I want to get into comedy' you're pushing at an open door," he said. "This year I think Sarah Millican will do extraordinarily well. She's a really funny comic. She isn't a funny 'female comic'. She's just a really funny comic.
"Suddenly people will hear of her and say 'Wow, she's great - she came from nowhere'."
He continued: "I guess she was doing something else last year. But it takes a relentless five or ten-year slog to get on to TV. You're out every night in clubs and there's something about that lifestyle which takes a certain type of... stupidity."
