Corey Monteith has checked into rehab. This is the 2nd time for the 'Glee' actor. He voluntarily admitted himself to a treatment facility for substance addiction. Monteith has previously opened up about his addiction and drug problems to Parade Magazine, even causing him to drop out of school at the age of 16.

His girlfriend from the show, Lea Michelle, loves and supports him. She stands by his decision, even tweeting, "Feeling so greatful today." 

We're sending our best thoughts to Cory, and hope he finds the help he needs!
