Glee actor Cory Monteith, 31, was found dead on Saturday evening at a Vancouver hotel.
A rep for for the late star said that they are in shock over this tragic news.
Monteith recently returned from a short stint in rehab for drug abuse, a disease he has battled with for years.
He was dating his co-star Lea Michele.
UPDATE: I have recently been notified that Cory Monteith died from “mixed drug toxicity” of heroin and alcohol, said the British Columbia coroner.
