Matthew Perry has spoken of his sadness following the death of Glee star Cory Monteith, a fellow recovering addict.

The actor was found dead in his hotel room in Vancouver, Canada on Saturday (13Jul13) and the former Friends star was particularly touched by his passing as they had both battled substance abuse issues in the past.

Perry is now sober after seeking treatment for drug and alcohol addiction twice, in 1997 and 2001, while Monteith recently completed his second stint in a rehab facility in April (13), after having admitted that he started using drugs at 13.

Speaking to NBC News on Monday (15Jul13), Perry admitted he has been struggling to find any positive angle to the 31-year-old star's passing, saying, "When something like this happens, it's so sad and tragic... it's just sad and tragic. The upside of it, I can't even talk about because there is no upside to this man losing his life."

Perry also noted that addiction is a nationwide epidemic, adding celebrities often wait too long before seeking help.

He explained, "Fame does one thing that really hurts alcoholics which is it makes them feel, if they buy into the press, it makes them feel that they're different. And that's something that we can't have."

The autopsy results which will determine the cause of Monteith's death are pending.
