Susanna Reid interrupted a live interview with Money Saving Expert Martin Lewis on Good Morning Britain.
The financial guru was talking about help-to-buy ISAs when the 48-year-old presenter cut in.
She said to viewers: "Just in case anyone is wondering why we are so distracted.
"Monsta X are here, they must have come in early."
The camera then panned to the six members of the South Korean K-Pop band and their entourage taking over the studio.
Susanna said there were crowds outside the London studio for the group, luckily Martin took the interruption well.
He later joked: "Now you can get on with the thing that was distracting you."
After a short break The boyband were forced to taste some traditional British delicacies, including black pudding, marmite and Scotch eggs.
The marmite did not go down well, with Honey having to request water because he found it so salty.
Fans loved the interview, one said: "Monsta X eating marmite was hilarious!"
Another said: "Never watched Monsta X on anything before but they’re killing me."
But some felt it was too much, one said: "Whose idea was this? This is cringy to watch."
