The cast of “Glee” — along with several producers — knew Cory Monteith was battling a heroin addiction earlier this year and were the catalyst in his decision to go back to rehab, TMZ has learned.
Sources connected to the production tell us … it was no secret Monteith was off his game back in March — and it became clear he was relapsing, specifically with heroin. We’re told the cast and the producers became very concerned … and knew they had to address the issue with Cory. Sources say … the group sat down with Cory and had an “open conversation” with the actor — stressing how much they cared about him and wanted him to get help. One source tells us Cory was very receptive — “It wasn’t met with resistance … He was always so grateful and aware of how fortunate he was.” “The decision was to best help our friend. The needs of the show fell second to his well-being.” Cory voluntarily checked into rehab at the end of March for a 30 day stint … but despite his efforts, he couldn’t defeat his demons, and last week, he died from a lethal mixture of heroin and alcohol.
