21 of 46: Aerosmith rocker Steven Tyler and guitarist Joe Perry were once dubbed 'the Toxic Twins' due to their drug and alcohol abuse, especially in the 1970s and 1980s. Tyler has undergone treatment at rehab centers and his latest stint in rehab came in late 2009, when he was treated for an addiction to prescription painkillers resulting from 10 years of performance injuries. He said in March 2011 that he has been sober for about a year and a half.

A day earlier, he suffered a fall in a hotel bathroom in the country.) (youtube.com/user/zsaint87)
