Cory Monteith, who played the adorable Finn Hudson on 'Glee,' was found dead on Saturday (July 13) in his hotel room in Vancouver, Canada at the age of 31.

According to TMZ, Monteith was found unresponsive and alone by staffers at the Fairmont Pacific Rim Hotel. The cause of death is unknown at this time, but the police have already ruled out foul play. Monteith was in his room the night before, hanging out with some friends before they all went out, but he had come back early Saturday morning alone.

The 'Glee' star voluntarily entered rehab back in April to address previous struggles with substance abuse. In a 2011 interview, he told Parade Magazine he began using drugs when he was just 13 and even sought treatment when he was 19 after his mother and close friends orchestrated an intervention.

“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 stated in 2011. "But for those people who might give up: Get real about what you want and go after it.”

Monteith was dating 'Glee' co-star Lea Michele offscreen, who was always by his side, even during his rehab stint. When he was admitted, she told PEOPLE, “I love and support Cory and will stand by him through this. I am grateful and proud he made this decision.” She has not responded yet to the news, but her camp has kindly asked the public to respect her privacy.

The last we heard of Monteith, he had finished his rehab stint on April 26. He was also working on several films (All the Wrong Reasons' and 'McCanick'), which may have been in post-production.

20th Century Fox Television and Fox Broadcasting company released a joint statement that reads:

“We are deeply saddened by this tragic news. Cory was an exceptional talent and an even more exceptional person. He was a true joy to work with and we will all miss him tremendously. Our thoughts and prayers are with his family and loved ones.”

So far there has been an outpour of tweets about the late actor, from co-star Dot-Marie Jones and peers like The Wanted, Nick Jonas, Rihanna, Demi Lovato, and Taylor Swift, among others.

Our thoughts and prayers go out to Cory Monteith and his family. We are devastated by the news.
