Cory Monteith

Fans and friends still mourning Cory Monteith got another blow at the Grammy Awards on Sunday night (Jan. 26).

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.

After weeks of skirting promos and press releases, 'Glee' season 5 has opened up for a full trailer of its forthcoming September 26 premiere "Love, Love, Love," chock full of Beatles tribute numbers, and little else. The gang is all smiles and songs in the first real run of footage from season 5, but how long until the bottom drops out?

'Glee's' memorial to the show's deceased star Cory Monteith will most likely be a tear-inducing event, but unfortunately, Dianna Agron wasn't invited. You know, even though Agron and Monteith's characters Quinn and Finn dated on and off for two seasons.

Lea Michele was understandably devastated by the death of 'Glee' costar and boyfriend Cory Monteith. Out of both respect for her and the late actor, all decisions about a tribute episode for Monteith were approved by Michele. Within the tribute episode, Michele and her character, Rachel Berry, paid their own tribute to Monteith -- by wearing a 'Finn' necklace. Quick, grab your Kleenex!

One of the last roles Cory Monteith played before his tragic passing from an accidental heroin overdose was, ironically, a substance abuser. Now we're getting a peek at Monteith in the dramatic role.

“Glee” has started filming its next season of the FOX TV show, just a few short weeks after the death of cast member Cory Monteith. The cast and crew are currently on the third episode of the season, the one that will directly address the actor’s passing, from referencing drug use to out-of-character PSAs reflecting on the actor’s life...

The Teen Choice Awards ceremony isn't typically known for its poignant moments, but on Sunday night, Aug. 11, Lea Michele brought the house (and a lot of viewers) to tears when she dedicated her surfboard to the late Cory Monteith.

'Glee' won the 2013 Teen Choice Award for Choice TV Show Comedy, with their star Lea Michele nabbing a surfboard of her own for Choice TV Star Comedy. The cast took their opportunity in the spotlight to dedicate their awards to the late Cory Monteith, as well as to their supporters following his death.
