Los Angeles, Jan 14 (IANS): Rapper Kanye West has been accused of attacking an 18-year-old after he used the N-word for him and his fiancee, socialite Kim Kardashian.

Kim was at a Beverly Hills medical building when she was swarmed by photographers. The guy allegedly tried to help Kim get in the building, and started screaming, "F**k these...n****rs" - referring to the paparazzi.

When Kim told him that it was not appropriate to use the N-word, he screamed at her, "F**k you b***h. Just trying to help you. Shut up N****r lover,..." reports tmz.com.

Kim then called up Kanye and when the guy realised Kanye was on the phone, he said: "F**k you N****r."
