Inside the Twitter Beef Between Kanye West and Deadmau5

Kanye is even involving his daughter North in the beef now.

The beef began when Kanye posted a photo to Twitter that, close up, appears to show the rapper with the file-sharing site Pirate Bay open on his browser alongside a tab featuring Serum, an editing software published by Deadmau5 and his music label, Xfer Records.

Deadmau5, whose real name is Joel Thomas Zimmerman, called West out on Tuesday, writing, "What the f--- @kanyewest ... Can't afford serum?"

West, never one to shy away from speaking his mind, responded yesterday with attacks on the DJ's persona and stage presence. (He performs wearing the head of a mouse.)

"whose job is it to carry the head on the plane # hash tag # do you check the mickey mouse head or carry on # does it get hot?" West wrote. "I’m bored ### when you get married will your wife have a giant minnie mouse head? # This brightened up my day… thank you dead-mow-five."

He then asked the successful producer and musician, "Do you do birthday parties?? My daughter loves Minnie mouse…"

Deadmau5 first responded to critics and fans of West, writing, "All is right with the world. Let's move on."

But then he responded to West directly, writing, "Imma let you finish.... But you should probably be saving the money for a 4th grade education ... I can out idiot an idiot. It's what I do."

This can and probably will continue, with more tweets to come.
