Cory Monteith in rehab for drug problems

Glee star Cory Monteith has checked himself into rehab for drug addiction.

Cory Monteith’s representative confirmed that the star, who has struggled with substance abuse in the past, has entered a treatment facility.

The actor “has voluntarily admitted himself to a treatment facility for substance addiction”, his spokesperson told People magazine.

“He graciously asks for your respect and privacy as he takes the necessary steps towards recovery.”

Cory Monteith’s girlfriend and Glee co-star Lea Michele told People magazine: “I love and support Cory and will stand by him through this. I am grateful and proud he made this decision.”

The 30-year-old actor has been open about his addiction problems in the past, and revealed back in 2011 that he entered rehab aged 19.

Cory Monteith hoped that talking about his own issues would help others to avoid making the same mistakes he did.

“I don’t want kids to think it’s okay to drop out of school and get high, and they’ll be famous actors, too,” he said.

“But for those people who might give up: Get real about what you want and go after it.”

Cory Monteith’s most recent tweet was posted on Thursday, when he wrote: “Such a beautiful day! truly seeing the forest for the trees. #gratitude.”
