Cory Monteith Memorial Details Revealed: "Incredibly Emotional and Moving," Says Glee Source

160 people gathered to remember and honor the late actor

More details about yesterday's memorial honoring Cory Monteith have surfaced.

A source who was in attendance during the memorial, alongside Monteith's girlfriend Lea Michele, Glee creator Ryan Murphy and other cast and crew, tells E! News exclusively that the gathering was "incredibly emotional and moving."

"Don't think there was a dry eye," the source adds. "It was a really fitting tribute to an amazing guy. But it is all just so sad."

Those who participated in the emotional celebration of Monteith's life included Glee cast and crew, writers and producers, Fox execs, close friends and family of the late actor. Some of Michele's close friends also flew in for it to support her and to remember Monteith. There were about 160 people at the memorial, which took place at Paramount studios where Glee films, and everyone wore black ribbons in honor of Cory.

Yesterday, Fox said in a statement to E! News, "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. We thank the public for their continued outpouring of love and support as we grieve our friend and colleague during this difficult time."

Monteith was found dead at age 31 in a Vancouver hotel room on July 13. Autopsy and toxicity results showed that the actor died of a drug overdose with heroin and alcohol found in his body. Monteith's last public appearance was with Michele on June 8 when Monteith walked his first red carpet since leaving rehab. Monteith, who first entered rehab at 19, had a long history of substance abuse.

Monteith's Glee costar Chris Colfer took to Instagram last night to remember his friend. "I'll never forget all the laughs we shared or the faces we made after awkward interview questions," Colfer wrote with a screengrab taken from a TV interview they did together. "Love and miss you, buddy."

Michele has yet to comment on the passing of her late boyfriend, but her reps said in a statement, "Lea is deeply grateful for all the love and support she's received from family, friends, and fans. Since Cory's passing, Lea has been grieving alongside his family and making appropriate arrangements with them. They are supporting each other as they endure this profound loss together. We continue to ask the media to respect the privacy of Lea and Cory's family."

Production of season five for Glee will begin Aug. 5, a week later than originally planned.
