Everyone knows that Kanye West is fiercely protective over his family, so it should come as no surprise that today (Jan. 13), he reportedly beat up an 18-year-old man who allegedly called Kim Kardashian a "n---- lover" and told the rapper, "F--- you, n----."

According to TMZ, Kardashian was walking into a chiropractor appointment in Beverly Hills when she was swarmed by paparazzi. A young, 18-year-old bystander supposedly tried to help her into the office, spewing off a slew of insults to the paps and saying, "F--- you f----t a-- n----s."

As much as she must loath the paparazzi herself, Kardashian obviously called the man out for using the N-word, to which he screamed, 'F--- you, b----. Just trying to help you. Shut up n---- lover, stupid slut."

Kardashian then called West, and, upon realizing who was on the phone, the man supposedly said, 'F--- you, n----."

When West arrived at the scene, he led his fiancé into the chiropractor's waiting room and found the teen sitting there. He then reportedly punched the guy in the face while Kardashian told him they have the whole incident on tape (presumably from the paparazzi).

West is now considered a suspect in the battery investigation and may be prosecuted, TMZ reports.
