A video has surfaced on the web of a man slapping Beyonce's mother, Tina Knowles, in the face.

In recent MediaTakeOut.com interview, the assailant explained what prompted the assault on Beyonce's mother. The fan explained, "I was trying to get an autograph and Beyonce was going to give it to me. But then that [EXPLETIVE] Tina opened up her big trap." The deranged fan continued, "So I just reached out and slapped her in the mouth."

And according to the fan, Beyonce got involved in the melee also. Tells the fan, "After I slapped [Tina], Beyonce tried to grab my hand, but I was too quick for her ... I just did what I had to do and kept it moving."

And the brazen fan isn't sorry for their actions either. Explains the fan, "I used to like Beyonce and her family, but not any more. They're real shady anyway ... and [Tina]'s face looked like it deserved a good slap."
