Cory Monteith

Cory's mother shared a heartwrenching post about Naya.

May 11 would have marked Glee actor Cory Monteith’s 33rd birthday, and his former co-star Lea Michele remembered her on- and off-screen boyfriend in a touching tweet.

Hard to believe, but the 100th episode of 'Glee' is fast approaching and the writing team is already working on ways to honor the late cast member Cory Monteith, who died of an accidental overdose in July of 2013.

'Glee' creator Ryan Murphy envisioned the last scene of the show and the series finale long before star Cory Monteith unexpectedly passed away.

Twitter has announced the top tweets of 2013 -- and the No. 1 most popular posting was also one of the saddest.

Cory Monteith's death shook the 'Glee' cast and crew to their core. The tribute episode to the star, who died of a lethal mixture of heroin and alcohol, will air this week. Titled 'The Quarterback,' it was the absolute hardest episode anyone on cast or crew has ever had to shoot.

Jane Lynch delivered an incredibly moving tribute to her fallen 'Glee' costar Cory Monteith at the 2013 Emmys.

Jane Lynch memorialized her 'Glee' co-star Cory Monteith, who died of a drug overdose in July at the tender age of 31, during tonight's (Sept. 22) Emmys telecast. Lynch told the world that Monteith was such a kind soul and so full of charm that it was incredibly easy to fall in love with him.

The Emmys will honor 'Glee' star Cory Monteith as part of a tribute to stars who passed away in 2013, along with James Gandolfini, Jean Stapleton, Jonathan Winters and Gary David Goldberg ... and not everyone is happy about it.

Since the death of 'Glee' star Cory Monteith last month, speculation has been rampant about how the show would deal with the departure of Monteith's character, Finn Hudson, from the series. Show creator Ryan Murphy later revealed that yes, Finn would be killed off -- but now further details have emerged about what will happen in the storyline.
