Despite the recent passing of "Glee" star Cory Monteith, Lea Michele and her fellow cast members will resume filming for season 5 next month.

Several former and current "Glee" actors have voiced their condolences and grief over Cory Monteith's death, including Jenna Ushkowitz, Dianna Agron, Chord Overstreet, and Charice Pempengco.

"I am so grateful that 'Glee' brought this group of extraordinary individuals together to form a family," wrote Ushkowitz on her 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."

"Cory always reminded me to be gracious, kind and open, and he will leave a mark in my heart forever. Thank you everyone for your constant support and love while we mourn the loss of our dear friend, and continued support to Cory's family, and to Lea."

Chord Overstreet also recently performed an original ballad at The Roxy in Los Angeles, stating, "This is for you, Cory."

Diana Agron, who shared a lot of screen time with Cory Monteith and Lea Michele, also voiced her grief at losing a friend for the first time.

"I have never lost a friend. In this difficult time, I am leaning on all of the wonderful memories we shared with Cory, how many ways he was able to make us smile. Glee was a gift to all of us. It gave us a family in this industry. We really cut our teeth and grew up on this show. In playing underdogs, we learned that we had dug into the hearts of our viewers and that we could stay there," wrote Agron in a heartfelt statement.

"Cory is so deserving of that place in everyone's hearts. He was one of the most generous and kind people that I have ever met. He had a smart, curious mind, he was an enormous talent. He was loving to not only me, but my family. My heart goes out to his family, to Lea, to everyone that is struggling with the loss of our friend. We will miss you Cory. We will always carry a piece of you with us."

And although Charice didn't share much time with Cory during her stint on "Glee," the singer shared a wonderful tribute about her time on the show cast members like Jenna, Chord, Cory, Lea, and Diana.

"My family was not there, my friends were not there, I didn't have my loved ones there to celebrate my birthday. It didn't help that we all still had a long way to go on that day at the set of 'Glee.' But Cory came to the rescue, just in time, with his sweet greeting: 'Happy birthday, Charice!' A big smile crossed his handsome face. There was sincerity in his tone as he gave me a tight hug. He became family to me at that moment."

"In the remaining hours of our shoot, Cory told me he had Googled me and found my date of my birth. Cool Cory's act of kindness. He told other members of the 'Glee' cast that it was my birthday and I was floored at how many of them greeted me with their warm birthday wishes."

With such heartfelt messages to Lea Michele and Cory Monteith, "Glee" season 5 will resume filming with grief counselors present for the cast.
