Deadmau5 has hit back at Skrillex after he called him an "a**hole".
The 'Bangarang' hitmaker - whose real name is Sonny John Moore - claims the dubstep musician helped him pursue his dream of being a famous artist, but criticised him for his "negative attitude".
In an interview on New York radio station AMP 92.3, he explained: "I'll always have love for Joel because he put me on at an early time, but he's an a**hole. And everyone knows that, and he knows that. And that's kinda his thing.
"The one thing that is unfortunate about it is he has a record label and when you have a record label you've got to be a leader and he has people that are signed to him. I couldn't imagine being a leader, going out [with] a public image being such a negative attitude."
However, Deadmau5 - whose real name is Joel Thomas Zimmerman - hit back with a series of tweets in which he acknowledged he can be a "f***ing diva" but insisted Skrillex should "let [him] worry about that s**t".
The 34-year-old DJ raged: "thanks for that pocket full of certified psychoanalysis. its really unfortunate i have a label. sorry for being me.
"at the end of the f***ing day, if im "miserable / moody / negative" then thats just me dealing with or not dealing internal s**t.
"yes. im aware that i can be a f***ing diva. yes i am aware than i have more than one complex. very f***ing aware.
"the people you should REALLY f***ing worry about, are the people who dont know it.
"so YES @skrillex im SUPER SAD im not as cheerful, and super inspired by life like you. and im so SORRY im an a**hole. but how about...
"you let me worry about that s**t. (sic)"
