The cast of Glee on Thursday held a private memorial service for Cory Monteith, who died two weeks ago from an overdose of heroin and alcohol at the age of 31.

“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,” 20th Century Fox Television said in a press release. “We thank the public for their continued outpouring of love and support as we grieve our friend and colleague during this difficult time.”

According to, more than 150 people attended the service, including Glee co-stars Kevin McHale, Chord Overstreet and Darren Criss.

Several cast members, including Chris Colfer and Jenna Ushkowitz, also posted remembrances on Instagram.

“I was lucky enough to closely experience the love and light that Cory shared with the world, as well as having the privilege of traveling down the road together on a once in a lifetime journey,” Ushkowitz wrote next to a Glee cast photo. “Cory always reminded me to be gracious, kind and open, and he will leave a mark in my heart.”

“I'll never forget all the laughs we shared or the faces we made after awkward interview questions,” Colfer wrote. “Love and miss you, buddy.”
