Steven Tyler has finally put a more realistic dollar figure on how much money he's, er, blown in his life.

Not that he hasn't already talked and written extensively about past drug use, but the Aerosmith frontman says in a new interview airing Sunday on Australia's 60 Minutes that he has probably snorted $5 million to $6 million worth of cocaine—not the $20 million he estimated in his 2011 memoir, Does the Noise in My Head Bother You?

"But it doesn't matter," he told reporter Liz Hayes. "You also could say I snorted half of Peru, but it doesn't matter. You know, it's what we did."
