The cast of the comedy drama came together to remember late actor Monteith.
The actor was found dead in a Vancouver hotel room earlier this month and his demise was deemed to be the result of a deadly mix of heroin and alcohol.
Cory played Finn Hudson on the American comedy sitcom, Glee, since its debut in 2009.His colleagues, including on-and-off-screen girlfriend Lea Michele, Dianna Agron, Jane Lynch, Amber Riley, Ryan Murphy, and others, have publicly mourned their loss since news of his passing broke.
"Today, Ryan Murphy and Lea Michele gathered the cast, crew and producers of Glee, along with colleagues from the network and studio, to share memories and music in an emotional celebration of the life of Cory Monteith," a representative from the Fox Network said in a statement.
"We thank the public for their continued outpouring of love and support as we grieve our friend and colleague during this difficult time."
After the poignant ceremony on Tuesday, actress Jane Lynch, who plays coach Sue Sylvester, said: "It was beautiful. And still really sad, but it was beautiful. It was nice to all be together again." Co-star Chris Colfer, who plays Monteith's step-brother Kurt Hummel on the hit show, broke his silence on Twitter today.
I'll never forget all the laughs we shared or the faces we made after awkward interview questions," he wrote. "Love and miss you, buddy."
Executives revealed last week that's Cory sudden demise has pushed back the premiere of Glee's fifth season. Filming will be delayed until early August and Season Five will premiere at the end of September.
Lea, 26, had been dating Cory for more than a year before he died.
Friends of the pretty actress are apparently concerned that she will never get over losing the love of her life.
"It seems so unfair and impossible to process. She's furious one minute and wracked with guilt the next," the insider explained to UK magazine Look. "I think she's wondering how she'll ever get over his death - and if that's even possible."
The group gathered at Paramount Studios in Los Angeles, where the show is filmed, to share stories as they remembered their friend and colleague, who died on July 13.
