Performing their hit song "Down and Dirty," Perrie shouted to the crowd, "F*** that, get down and dirty!"
It's not really a huge deal, right? Well... wrong.
Their performance was being live streamed, and after the F-bomb was dropped, they completely cut the broadcast off, with host Matt Edmondson issuing an apology.
"So... apologies there, sincere apologies for any bad language you might have heard. Obviously that was not intended to go out on the radio."
Geez. Tough crowd.
Fans who were watching the livestream were not happy that one slip up meant they had to cancel the entire thing.
Seems a bit harsh...
