As the show progressed, more viewers took to Twitter to express their confusion over Jimmy’s new look.

Amanda or Jimmy Carr.‘

Paddy McGuinness takes centre stage to present the musical competition, while Jimmy is on a panel with Amanda Holden and Alison Hammond.

Jimmy has spoken candidly about the full extent of his makeover in the past.

Talking on Gabby Logan’s Midpoint podcast, Jimmy said he decided to make some tweaks to his appearance after feeling disappointed that he doesn’t look as good in real life as he does on television.

He said: ‚I got my teeth done, that’s the first thing I had done, they’re more than veneers.

I got every tooth in my head done in one sitting.

‚I did 12 hours in the chair the first day, then 12 hours the second, it was like a three day thing where you’ve got temporary things on, it’s pretty full on.

‚I think they gave me Rohypnol intravenously into the vein and you’re kind of out of it and they do everything and you’re fine.

It’s a dream-like haze, you’re in a weird space.‘

Jimmy said he wants to maintain his looks rather than change them too much.

He said: ‚I think that thing of age is that people don’t really see what’s there, people are good at pattern recognition, that’s all they do, teeth and hair.

Jimmy said: ‚I’ve had a lot of work done.

I got my teeth knocked out and put back in.
