Singer/reality star Ray J got into a physical altercation early Friday morning (March 22), sparked when he called a woman a “fat bitch.”

In footage obtained by TMZ.com, the singer is seen being yelled at by a woman after he hurled the “fat bitch” insult at her, backstage at Club Nokia in Los Angeles at around 1 a.m.

Ray tried to calm her down to no avail, before getting into a physical altercation sometime later with an unknown man.

It’s unclear how the fight started, but no one was arrested.
