It took me forever to find this book for some odd reason, but I hadn't come across this story before.
Nikki: The next day was the kickoff of the Monsters of Rock minitour. While we were traveling in the States with Ratt, we had gotten into the habit of biting each other. Tommy would grab Vince or a security guard, and clamp his teeth down on an arm until he broke the skin. It was all affectionate, of course, but it hurt like hell if you weren't fucked up.
I was so drunk and coked up at that fist show that I walked up to Eddie Van Halen and tackled him. Then I reared my head up, lifted his shirt, and sank my teeth into his bare stomach. "What the fuck is wrong with you?" his wife Valerie Bertinelli, bellowed. "Biting my husband? You fucking freak!"
Eddie stood up, dusted himself off, and narrowed his squinty eyes. I couldn't tell whether he was turned on or offended. Before I had a chance to apologize, Vince ran up to him like a savage dog and sank his teeth into his hand. And that threw Valerie into hysterics: Nobody bites the hand that Eddie Van Halen uses to play guitar with.
