BBC Saturday Kitchen's Matt Tebbutt red-faced after guest's brutal swipe live on air

Saturday Kitchen star Matt Tebbutt was left red-faced after a guest's brutal swipe live on air.

During today's (July 19) edition of the hit BBC cooking programme, the 51-year-old presenter was joined by drinks expert Helen McGinn and chefs Hasan Semay and Luke Holder.

Motherland and Cunk on Earth star Diane Morgan also appeared on the show to promote the fourth instalment of her BBC comedy series, Mandy.

During the live show, Matt made a plant-based cheesecake for Diane after she changed her diet back in January.

"I love a dessert, and it's very difficult to get a good plant-based dessert," she said, with Matt adding: "Until now."

The host continued: "It's delicious... We ate it in rehearsal and it's really, really good."

Matt explained that had had substituted mascarpone for tofu, which was mixed with corn flour, lemon zest, vegan cream and vanilla. He also added coconut oil to the biscuit base instead of butter.

At the table, Helen shared her surprise at the dessert being vegan, saying: "I would not have guessed. It's absolutely delicious."

However, Diane wasn't as pleased with the dish after having a mouthful.

"How is it?" Matt asked, with the actor hesitantly replying: "Yeah it's nice."

"You can't be that fussy!" Matt then said, causing the rest of the studio to erupt into laughter, before the host quickly changed the subject.

Later on, Diane made another swipe at the cheesecake after trying plant-based mochi, saying: "No offence to the cheesecake but this is delicious."

After watching the awkward exchange, several of the show's viewers quickly took to X (formerly Twitter) to comment on Diane's reaction.

"Diane Morgan could've been a bit nicer about the dessert," one person wrote.

Another added: "Diane Morgan hates that cheesecake on #SaturdayKitchen. So awkward," while a third said: "Diane Morgan is making Matt Tebbutt nervous."
