From Radar Online By Gina Bacchiocchi: Like his fans, Naya Rivera was shocked by her close friend and Glee costar Cory Monteith‘s death from a heroin overdose at just 31. But more than three years later, she now recognizes the signs she missed before he succumbed to his addiction, the 29-year-old actress reveals in her new book, Sorry Not Sorry: Dreams, Mistakes and Growing Up.
After Monteith began drinking following years of sobriety at the season three wrap party, the cast noticed his strange decision, she recalls.
“He explained that he wanted to be able to drink in moderation, that he could do it and be just like everybody else,” the now-married mom writes. “He seemed calm and confident about it, so we all just accepted it.”
“To be honest, I don’t think many of us really understood how addiction worked, nor did we fully realize the extent of his former addiction.”
Rivera and her costars did not think that their “sweet, smart, talented” friend could possibly be doing heroin again.
