Richard Madeley briefly walked off the live set of Good Morning Britain on Tuesday after co-host Kate Garraway teased him about his pet peeve of people eating food next to him.
The incident occurred on the ITV morning show just before handing over to This Morning hosts Alison Hammond and Dermot O'Leary.
Madeley, 70, had expressed his strong dislike for hearing people chew food, particularly while watching films at movie theaters.
In response to his confession, Garraway, 59, pulled a bag of popcorn from inside a coffee table cabinet on set and began eating it next to him during the live segment.
"He's the fun police - he doesn't like people eating next to him," said Garraway.
Madeley sighed, reacted with disgust, and exited the studio stage, prompting his co-presenter to address the sudden departure on air.
"He's had enough, he's stormed off set!" said Garraway.
Madeley returned to his seat next to Garraway following a short promotional preview from Hammond and O'Leary, shortly before the program went to a commercial break.
The broadcast moment follows a series of recent live disruptions on the show.
During a live broadcast on Friday, Garraway issued an apology to viewers after a passerby made an offensive hand gesture behind a guest who was being interviewed in Edinburgh.
Tribute to Bill Oddie and New Weather Presenter
Earlier on the show, Madeley also paid tribute to legendary wildlife presenter and comedian Bill Oddie, whose representative David Foster announced on Monday that he had died at the age of 85.
"It is with deep sadness that I announce the passing of Bill Oddie, the country's best-loved birder," said Foster.
"Bill was a multi-talented celebrity - wildlife presenter, broadcaster, comedian, writer, songwriter, musician and conservationist. Yet it was never fame that he valued," said Foster.
Madeley reflected on his past professional experiences interviewing the late conservationist during the morning broadcast.
"He was spikey, you really had to get your boxing gloves out when you interviewed him. You couldn't say the wrong thing," said Madeley.
The Monday episode of Good Morning Britain also featured meteorologist Chris Page making his debut appearance on the national broadcast, temporarily filling in for regular weather presenters Laura Tobin and Alex Beresford.
"We've got a new weather guy today! If you are in the Anglia region, you'll know him - he's been doing it for years there.
But he's got up very, very early and he's come all the way down from Norwich. Here's Chris with the weather," said Madeley.
Page provided a regional weather forecast predicting elevated temperatures and potential heatwave conditions across parts of the United Kingdom later in the week.
