Kanye West allegedly attacked an 18-year-old man after he screamed a racial slur at his fiancée Kim Kardashian.

According to TMZ, Kim was entering a medical office in Beverly Hills on Monday when she was swarmed by paparazzi. The 18-year-old tried to help Kim by holding open the door so she could get in.

As Kim walked, the man allegedly said, “F**k these fa**ot-ass n****rs,” referring to the paparazzi. Kim then told him it was not appropriate to use the N-word.

He reportedly shot back, screaming, “F**k you bitch. Just trying to help you. Shut up n****r lover, stupid slut.”

Kanye arrived soon after and burst into the waiting room of chiropractor Richard Hill to confront the 18-year-old. According to witnesses, Kanye punched the guy and Kim screamed, “We have it all on tape.”

A massage therapist reportedly stepped in to separate the men. Police were called and the 18-year-old said that he wanted to press charges.

Kanye is now officially a suspect in a battery investigation and police want to interview him. The L.A. County D.A. will also decide whether to prosecute him.
