0427_cory_monteith_getty_article1Cory Monteith has something to sing about -- the "Glee" star successfully completed his month-long treatment for substance abuse, according to reports.

Monteith voluntarily checked himself into a treatment facility at the beginning of April, admitting he had a "substance addiction." It was the 30-year-old's second time getting help.

On Friday, sources confirmed to People that Monteith had completed his stint in rehab after close to 30 days of treatment. He was spotted at LAX, free as a bird, with on-and-off-screen GF Lea Michele.

Now if only he could graduate from "Glee."
