(TMZ) Kanye West just attacked an 18-year-old guy inside the waiting room of a chiropractor's office ... TMZ has learned.
Kanye and Kim were in Beverly Hills when they were swarmed by photogs. We're told the 18-year-old came to Kim's rescue and held the door of a medical building open so she could get in.
As Kim walked, the guy 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. We're told he then screamed at her, "F**k you bitch. Just trying to help you. Shut up n****r lover, stupid slut."
Apparently that got Kim hot as fish grease ... she watched the guy walk into an office. A short time later Kanye arrived and went into the office.
Sources say Kanye and Kim rushed into the waiting room of chiropractor Richard Hill and found the 18-year-old sitting there. Witnesses say Kanye punched the guy and Kim screamed, "We have it all on tape."
Sources say the massage therapist in the office separated the 2 men. Beverly Hills cops were called and the 18-year-old said he wanted to press charges.
