Calvin Harris has been recorded calling a crowd member a "daft f**king bitch".
The DJ was playing a gig at Miami's LIV Nightclub on Thursday (August 29), when a concert-goer began heckling him.
She is heard calling him a "sellout" and asked him to "play something original".
In response, Harris said to her: "That was originally written by me. That's my song."
Soon afterwards, Harris added: "Why do you come to a f**king Calvin Harris show where Calvin Harris is DJ-ing and don't want to hear a f**king Calvin Harris record, you daft f**king b*tch."
Calvin Harris recently topped a list of the world's highest-paid DJs, reportedly earning £30 million over the last 12 months.
