This is not the first time Perry has opened up about his struggles with Vicodin and alcohol. In August, the actor gave a very candid interview with the Hollywood Reporter, where he explained, "You can't have a drug problem for 30 years and then expect to have it be solved in 28 days," adding, "Getting sober is a really hard thing to do."
In 2013, Perry -- who has been to rehab twice -- turned his former Malibu home into a sober living facility called Perry House.
With the exception of Perry, whose rep told ET that he couldn't join due to a scheduling conflict -- the actor is currently preparing for his upcoming play, The End of Longing -- the whole gang got together over the weekend to participate in a tribute broadcast honoring legendary TV director James Burrows. It marked one of the rare appearances of our favorite Friends ever reuniting since the show went off the air in 2004.
