The Lonely Boy rocker plucked up the courage to say hello to the Walk on the Wild Side singer in the hope they could chat about the death of his cousin, Voidoids guitarist Robert Quine - but Lou just brushed him aside.
"I heard a lot of Lou stories from my cousin... (and) then The Black Keys were playing a fundraiser with Lou right after Robert died in 2004," he told Rolling Stone magazine.
"So I walk up to Lou and say, 'I'm playing in The Black Keys here. My cousin was Robert Quine. He told me how much he thought of you'. Lou stared in my eyes, and just turned around and walked away.
"Ever since I met Lou, I don't really have heroes anymore. Or, at least, I don't want to meet them."
