Listen to Steven Tyler on iHeartRadio

Steven Tyler estimates his past cocaine habit probably cost him upwards of five million dollars.  In an interview with Australia's 60 Minutes last week, the Aerosmith frontman told the TV program he "snorted half of Peru" in his early days as a rock star and probably spent between five and six million dollars to do it. 

Tyler was responding to a claim he made in his memoir "Does the Noise In My Head Bother You?" in which he said he spent 20-million-dollars on cocaine in the 1970s and '80s. 

He told the show this week that the number in the book was exaggerated, offering up the adjusted numbers as more realistic. 

Tyler has been candid about his former drug addiction in recent years - the highs and lows of it all.  In a 2011 interview with Matt Lauer for NBC's "Dateline," the 64-year-old rocker said at his worst he needed cocaine but added that it also took his children and his marriages away. 

Having had more than a few stints in rehab over the years, the former "American Idol" judge  considers himself sober these days.
