Joe Perry took to Twitter on Tuesday (November 13th) to let his fans know that he is doing fine after facing a medical emergency on Saturday (November 12th). Perry made a special appearance at a Billy Joel concert in NYC and reportedly collapsed backstage afterwards. Although the 68-year-old was “alert and responsive” after going to the hospital, the cause for the emergency is still uncertain. The Aerosmith member tweeted, “Doing well, thanks for all the love and support!”

Doing well, thanks for all the love and support!
