Watch: Chris Tarrant doesn't watch Jeremy Clarkson's Who Wants To Be A Millionaire?
The TV presenter hosted the hit ITV quiz from its beginning in 1998 until 2014, when it was cancelled, but a revived version in 2018 put former Top Gear host Clarkson in charge.
But despite spending more than 15 years on the show, Tarrant, 76, has admitted that he doesn't settle down to watch the reboot.
Speaking to Kate Garraway and Richard Madeley on Tuesday's Good Morning Britain, Tarrant was asked whether he watched Clarkson in his old role.
He quickly answered: “Do you know I haven't, I don’t know why.
“I did 700 shows and I only watched two of them, so why would I watch Jeremy's [version]?”
Tarrant also offered a brief apology to GMB presenter and Tipping Point host Ben Shephard as he admitted to not really being a fan of game shows in general.
On his TV viewing habits, he said: “I don’t watch game shows. Sorry, Ben, but I watch Netflix, Sky Sports, dramas, that's it really. That’s about 24 hours.”
Madeley, who was interviewing him, recently took part in a celebrity episode of Who Wants To Be A Millionaire? but made a blunder when he gave one answer calling host Clarkson "Chris".
Clarkson told him: "I’m not Chris,” as Madeley replied: "Does that happen [often]?"
When Tarrant quit his role hosting the quiz in 2014, he said that he had loved the show and felt very lucky to have done it, but needed a break.
He added: "I am privileged to have been a part of it, but do now feel that it is time for me to call it a day.
"I've worked ridiculously hard these last few years and to quote myself, 'it's time to take a break'."
When the rebooted version was announced with Clarkson at the helm, Tarrant's reps revealed he had not been approached for his old job.
They said: “Chris thought the programme had run its course. He wasn’t approached but if he was, he would have politely turned it down.
“Chris is delighted it’s back and wishes it well.”
