Sam Smith was reportedly left furious after their BRITs performance was almost cancelled due to technical difficulties with their £500,000 set.
The singer, 30, who is non-binary and uses gender neutral pronouns, is believed to have been arguing backstage over the delays caused by the malfunctioning set for hit Unholy on Saturday.
Sam allegedly kicked up a fuss as crew tried to fix the technical issues on the set which affected the live TV awards ceremony's schedule and resulted in a video montage of Adele briefly appearing on our screens.
