Monteith would have been 32 Sunday. The former Glee star died in July 2013 from a toxic mixture of heroin and alcohol. His character, Finn Hudson, was written out of the series in the touching, emotional episode "The Quarterback" (watch it here). In February, Michele released a tribute song in his honor.
