UPDATE: Glee co-creator/exec producer Ryan Murphy tweeted support for Monteith this morning. “I am so proud of Cory Monteith and love and support him 100%,” he wrote.

PREVIOUS: Glee star Cory Monteith has checked himself into rehab for substance addiction. The Fox musical dramedy has two more episodes from its current fourth season left to shoot. Filming on them will proceed as scheduled, with the sudden absence of Monteith’s Finn explained. “Cory is a beloved member of the Glee family and we fully support his decision to seek treatment,” Glee producer 20th Century Fox TV said in a statement. “Everyone at the show wishes him well and looks forward to his return.” Along with Lea Michele and Chris Colfer, Monteith has been prominently featured this season despite his character graduating from McKinley High last May. This is not Monteith’s first stint in rehab. The actor has been open about his addiction problems in the past and two years ago revealed that he entered rehab when he was 19.
