Actor Cory Monteith has checked into a rehabilitation center to address substance addiction issues.
The 30 year old, who is dating his Glee co-star Lea Michele, voluntarily sought professional help to face up to his problems.
His representative tells People.com, "(Monteith) has voluntarily admitted himself to a treatment facility for substance addiction. He graciously asks for your respect and privacy as he takes the necessary steps towards recovery."
Michele adds, "I love and support Cory and will stand by him through this. I am grateful and proud he made this decision."
Monteith has been open about his drink and drug habit in the past, revealing in 2011 that he had previously checked into rehab when he was 19 years old.
