Criss said Monteith, who died on July 13 at age 31 of a heroin and alcohol overdose, was a "wonderful guy" and the cast and crew were "picking up the pieces" since losing him.
"He was a really funny guy, had a great sense of humor and he really loved life," Criss said. "He always took care of his friends and wanted his friends to be happy."
Criss added: "He'll be severely missed. But I'm just so happy that a guy like him got to touch as many lives as he did while we were all lucky enough to have him."
