Glee star Lea Michele is reportedly "devastated beyond belief" following the tragic death of her boyfriend Cory Monteith.
The 26-year-old actress has released a statement asking for "privacy at this devastating time".
According to sources for Hollywood Life, "she is absolutely hysterical and completely inconsolable.
"She is devastated beyond belief."
The New Yorker is reeling from the news that her Glee co-star and boyfriend of two years died in a hotel in Vancouver, Canada.
The 31-year-old was found alone in his hotel room on Sunday morning.
The Canadian star was staying in a luxury room at the Fairmont Pacific Rim hotel when he went out with friends on Saturday night.
It is believed that Lea - who plays Rachel Berry in FOX's musical comedy-drama - was not with the group.
Lea spoke about her relationship with Cory - who was Finn Hudson in the show - to Marie Claire earlier this year.
She said: "I don't even remember a time when he wasn't my boyfriend. No one knows me better than Cory.
"No one knows what it's been like to go through this more than he does.
"Feeling like you have that net underneath you allows you to jump higher and go farther. He makes me feel like I can do anything.
"For the first time in my life, I feel really, really settled and happy.
"I feel like the luckiest girl in the world."
No cause of death has been announced but there is said to be no suggestion of foul play.
An autopsy will take place on Monday.
Cory had completed his second stint in rehab in April after admitting himself for substance abuse issues.
He had previously said he felt "lucky to be alive" after years of addiction.
An insider told E! News: "He was super committed to getting sober. He would say this was his last chance."
The star of Glee had been active on Twitter before his death, joking about the upcoming film Sharknado.
He wrote in his last tweet: "What the c**p is Sharknado... Oh. IT'S A SHARK TORNADO."
Cory was much loved and messages of sadness have flooded in from various stars and friends.
Selena Gomez tweeted a picture and her deep sadness over the loss.
Co-star Matthew Morrison was performing a concert and dedicated it to the passed star.
He said: "You guys came to see a show, I came to perform a show, so that's what we'll do. And we'll do it in Cory's honour."
Gwyneth Paltrow, who also appeared in Glee, released a moving statement in tribute: "Cory was a sweet and talented man. My heart breaks for Lea and the entire Glee family."
Fellow Glee actor Harry Shum Jr tweeted: "At this time, please send nothing but love and light. This tragic news still doesn't feel real to me."
Dot-Marie Jones, also an actor on the show, wrote: "I am blessed to have worked with him and love him so much!
"My heart is with his family and our whole Glee family! I love you all!
I have no words! My heart is broken. Cory was not only a hell of a friend, he was one amazing man that I will hold close to my heart forever."
A statement from broadcasting company FOX, which airs Glee, called him an "exceptional talent and an even more exceptional person.
"He was a true joy to work with and we will all miss him tremendously."
Many more who knew him have expressed their sadness at the news.
