Matthew Perry, one of the stars of the smash hit TV sitcom "Friends," was found dead at his home Saturday, US media reported. He was 54.

First responders found Perry unconscious in a hot tub at his Los Angeles home and were unable to revive him, law enforcement sources told the Los Angeles Times.

Perry was best known for his portrayal of the wise-cracking Chandler Bing on NBC's wildly popular "Friends," which ran for 10 seasons from 1994 to 2004.

Perry had battled for years with addiction to painkillers and alcohol, and attended rehabilitation clinics on multiple occasions.
