Do not mess with Nikki Sixx.

Motley Crue member Nikki Sixx sticks up for his bandmates in his own unique way...
Star Pulse:
Motley Crue rocker Nikki Sixx was so infuriated when a bottle of urine was thrown at singer Vince Neil during a gig, he punched the fan responsible backstage after the show........."He was brought back, and I told the security guys to leave us alone. I had a word or two with him. And, yeah... he apologized."
