Matthew Perry has revealed how "painfully hungover" he was during the height of his fame filming 'Friends'.
The actor, who played Chandler Bing for 10 years, opened up to People Magazine about his former prescription pill and alcohol addictions.
However, he insists he was never actually high at work and it wasn't until “things got so bad [he] couldn’t hide it" that everybody knew.
In 1997 Perry went to rehab for a Vicodin addiction and was then admitted again in February 2001 to reportedly treat addictions to pills and alcohol.
Perry is now clean and helping other addicts, having turned his Malibu mansion into a sober-living home called Perry House.
