The news arrived today that Bitten Knudsen, a Danish-born fashion model, darling of the disco era, best buddy of the famous train wreck Gia Carangi, and one of my favorite models of all time died in her sleep on March 22 in Denmark. Bitten, who was featured in my book, Model, was an unapologetic bad girl who called herself The Kid and the multitude of men who chased her dogs. “As bad as you are, that’s how good you can be at your job,” she said. She was good bad, not evil. R.I.P., beauty.
