Ahead of the airing of the FRIENDS reunion, the cast members sat down with People magazine for a short segment called "The One Where They Answer Three Questions".
Perry's behaviour drew the attention of eagled-eyes fans, with some raising concerns about his health.
The actor was also defended by people who said he was probably being emotional while talking.
Following an accident around 1997, Perry became addicted to Vicodin and alcohol. He was in his late twenties then. The effects of his addiction can be traced through the seasons of FRIENDS – where Perry's weight fluctuated drastically, once dropping down to just 145 pounds (66 kg). In 2000, Perry lost more 20 pounds due to pancreatitis.
Though he emerged victorious from his Vicodin addiction, in recent years several images clicked by paparazzi appear to show him growing old and looking ill, causing fans to be concerned about his well-being.
FRIENDS fans have also been critical of Courtney Cox's botox-injected face in the past.
The latest trailer for the FRIENDS reunion clarifies that this will not be an episode where the actors give fans a glimpse into their characters' old lives. Rather, the episode will get them all together again to stroll down memory lane about shooting a show that went on to become a global phenomenon.
Along with the cast of the show, a star-studded line up of more celebrities will be featured in the epic reunion of FRIENDS – including Justin Bieber, BTS, David Beckham, Kit Harrington, and Reese Witherspoon, among others.
