Keep it classy, Kanye West fans.

If you're not aware of the latest installment in the long-running feud between Kanye West and Taylor Swift, we're not going to go into it here. Look, just read these links. Suffice to say that the blood remains bad between the rapper and the pop star.

West played in Swift's adopted hometown of Nashville the other night, and wasted no time in making his feelings known during the song 'Famous', where he raps 'I made that bitch famous'.

According to reports, he re-started the song three times to hear the crowd shouting those words back at him, saying "I need to hear that loud in Nashville. I need to hear that so loud in Nashville. I feel like I' in a movie right now, or something.

"So many people told me, ‘You’ve gotta take that line out of the song. You gotta play it safe.’ This is what rap music is; this is what art is.”

The crowd then began to chant 'F**k Taylor Swift', which you can see below:
