Cory Monteith has checked into rehab for substance abuse issues, his rep tells TVGuide.com.
The Glee star "voluntarily admitted himself into a treatment facility for substance addiction," his rep said. "He graciously asks for your respect and privacy as he takes the necessary steps towards recovery."
Monteith's Glee co-star and offscreen girlfriend, Lea Michele, said she supports him seeking treatment. "I love and support Cory and will stand by him through this," Michele told People, which was the first to report the news. "I am grateful and proud he made this decision."
Glee is still in production on its fourth season and filming will proceed as scheduled, Deadline reports. Monteith's character, Finn, will not appear in the final two episodes of the season and his absence will be explained.
