NEW YORK: ''Glee'' star Cory Monteith is heading to rehab, according to People.    

Monteith's rep told the magazine that the actor has ''voluntarily admitted himself to a treatment facility for substance addiction''.

People reported the news Sunday night on its website.

This is not the 30-year-old's first time in rehab. He got treatment when he was 19 and has spoken about his addiction struggles, saying he had a serious problem and took just ''anything and everything.''

He told Parade in 2011 that he was ''lucky to be alive''.

Monteith stars as Finn Hudson on the Fox show. He dates his co-star, Lea Michele. She told People that she loves and supports Monteith and is proud he's going to rehab.
