Tragic news out of Hollywood: Glee actor Cory Monteith, who played Finn Hudson, has been found dead in a hotel room in Vancouver, Canada, aged 31.

The actor spent Saturday night at the luxury hotel with friends, but was found dead in his room by staff on Sunday morning.

Co-star and girlfriend of two years Lea Michele has asked for privacy. “We ask that everyone kindly respect Lea’s privacy during this devastating time,” her rep said in a statement.

Fellow co-star Jane Lynch spent the day – her 53rd birthday – alone in New York, visibly upset. And another co-star, Matthew Morrison, dedicated a song to Monteith, who he called his “brother”, in his Broadway show 54 Below in New York City, on Sunday.

Glee’s executives producers released a statement: “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.”

Monteith had battled drug addiction, completing a month-long rehab treatment in April, with Michele standing by him.

“I love and support Cory and will stand by him through this,” she said at the time.

Following treatment, Monteith tweeted: “Sending out big love to everyone. thank you for the continued support! It means the world to me! :)”

On the same day Michele wrote: “Today is a great day

Love you all! Xo.”

The couple then celebrated with a romantic holiday in Mexico together.

An autopsy will be performed on Monday.
