A witness tells New York Post gossip column PageSix, "A woman from the tribe was trying to take a picture of Steven Tyler. Steven's girlfriend was coming back, from the restroom. Apparently, Erin got in the way of the picture or something, and some words were exchanged.

"Next thing everyone knows, the two girls are going at it. Scratching, hair-pulling, hitting. It lasted about six seconds, then security broke it up. Steven got up to try to pull them apart, but it happened so fast, he really didn't have time to do anything. Security was right on top of it." - more on this story
