Premise: Steven Tyler . While tension with his Aerosmith bandmates boiled in 2009 and 2010 after he fell off the stage at a concert , had a relapse with prescription drugs ( which he successfully received treatment for in 2009 ) , and signed on to American Idol without telling his bandmates , Tyler has continued to record music and perform with Aerosmith , after more than 46 years in the band .
Hypothesis: Steven Tyler has never had a drug addiction problem.
