Darren Criss, GLEE Cast & More React to Monteith Tribute on Twitter

Last night, FOX aired a Glee tribute episode to fallen cast member Cory Monteith. The actor passed away on July 13th due to an accidental drug overdose. The emotionally charged episode, titled 'The Quarterback,' focused on Monteith's character Finn Hudson, a former star football player for the fictional McKinley High.

Set entirely in Lima, Ohio, home of the high school, the episode opened with the news of the athlete's death and went on to focus on all the characters remembering and mourning him, and celebrating his life.

Below, read how Glee cast members and other celebrities reacted to the emotional tribute on Twitter:
