Good Morning Britain’s Susanna Reid was left red-faced after introducing Michael Underwood by the wrong name.
The embarrassing blunder took Michael, 41, by surprise and host Susanna was shocked at her own mistake.
Susanna, 46, introduced Michael saying: “We’re here with Michael Underwear.”
The star immediately realised her mistake and threw her hands over her mouth.
A stunned Michael said: “Michael Underwear?
“Wow. She actually said that.”
And of course co-host Piers had to get his say in as he said: “Is that what you call him? Oh my God.
“We only call him that off camera.”
Showbiz correspondent Michael attempted to change the conversation by saying: “Anyway, good morning.”
But a still shocked Susanna asked: “How many times have you ever been called Michael Underwear?”
To which Michael replied: “Once, today, and well apart from obviously the horrendous school memories.”
Controversial Piers then interrupted saying: “Well done Susanna, bringing back his mental scars.”
Viewers were amused by the gaffe as one tweeted: “‘Michael Underwear’? What’s Susanna got on her mind in order to make that mistake?! #gmb.”
Another added: “@GMB Love the underwear comment Susanna made me chuckle …ooops!!”
“@GMB Michael underwear .. you made me laugh Susannah,” a third wrote.
