Glee star Cory Monteith has been found dead in a hotel room in Canada, Vancouver Police have confirmed.
The 31-year-old's body was discovered at Vancouver's Fairmont Pacific Rim hotel just after noon on Saturday after he failed to check out.
Police believe he was alone when he died, and have ruled out foul play.
Doug LePard, the acting chief of Vancouver Police, said: "As was the case in countless homes, I watched Glee regularly with my daughters, and I know there will be shock and sadness in many households with the news of his tragic death.
"Mr Monteith checked into the hotel on July 6 and was due to check out of the room (on Saturday).
"There were others with Mr Monteith in his room earlier ... but video and fob key entries show him returning to his room by himself in the early morning hours and we believe he was alone when he died."
Monteith had voluntarily entered rehab for substance abuse problems in April.
It was not Monteith's first time in rehab. He received treatment when he was 19 and had previously talked about his addiction struggles, saying he had a serious problem and took just "anything and everything".
He told Parade magazine in 2011 that he was "lucky to be alive".
He was best known for playing Finn Hudson in the popular musical comedy series Glee, which follows a group of American secondary school misfits.
A post-mortem will take place on Monday, and the coroner will decide on the next steps to establish the cause of death.
