Steven Tyler has opened up on his drug usage during his pomp as a global rock star. The Aerosmith frontman suggests he snorted “half of Peru”, according to celeb gossip site, TMZ.

Talking on Australia's "60 Minutes", Tyler said he spent loads of cash on the drug. "Probably, realistically, 5 or 6 [million], easy ... You could also say I snorted half of Peru, but, you know, it's what we did," he said. Since then, Tyler has kicked the habit, but not before it left him in a pretty bad way. He told Matt Lauer back in 2011, "I needed that cocaine. I needed it." But he said it ruined him, adding, "It took my children away, it took my marriages away. I was on my knees."

Steven Tyler and Joe Perry are among the latest inductees into the Songwriters Hall of Fame. "Each of our 2013 inductees has been responsible for captivating the world with their creativity for decades, serving up a rich variety of songs for our global soundtrack," said Hall chairman Jimmy Webb in a release. "We are looking forward to celebrating their contributions at our Annual Awards Gala."
