Celebrities are taking to their Twitter to pay their respects and express their grief in regards to the sudden death of singer and songwriter Amy Winehouse, who was found dead at her London home on Saturday.
The cause of death is still unknown for the Grammy Award winning artist, only 27-years-old at the time.
Many are suspecting that her death may possibly be the result of her long-term battle with substance abuse, having also struggled previously with manic depression and eating disorders.
Best friend and fellow singer Kelly Osbourne, who had previously helped the late singer check into a drug addiction treatment facility in 2008, according to The Associated Press, tweeted her disbelief.
“I can’t even breath right now i’m crying so hard I just lost 1 of my best friends. i love you forever Amy and will never forget the real you!”
Other stars took the time to tweet their respects as well, including Rihanna, Jessica Alba, Ashton Kutcher, and Kate Moss.
Rihanna: “I am genuinely heartbroken about this,” and “Dear God have mercy!!! I am SICK about this right now!”
Jessica Alba: “So sad about Amy Winehouse- she was so talented. Really tragic.”
Ashton Kutcher: “I nevr know wht 2 post after paying respect 2 sum1 who died. Just seems lk anything funny is inappropriate. mayB I’ll just go C Harry Potter.”
His wife, Demi Moore also tweeted: “Truly sad news about Amy Winehouse. My heart goes out to her family. May her troubled soul find peace.”
Fellow Brits Kate Moss and Lily Allen shared, “R.I.P. Amy Winehouse, So upset, my heart goes out to her, sad to see such talent vanish from the world.”
Allen: “It’s just beyond sad, there’s nothing else to say. She was such a lost soul, may she rest in peace.”
Richard Roeper found it surprising that several singers also died at 27. “Jimi Hendrix, Janis Joplin, Jim Morrison, Brian Jones of the Rolling Stones, Kurt Cobain and now Amy Winehouse: all died at 27.”
Moby, who was last with Winehouse during her infamous drunken performance last month in Serbia where she was booed off stage, also expressed his feelings via Twitter.
“After our show in Serbia I wish I’d been able to help amy. I’m sorry,” he tweeted.
Winehouse’s autopsy is scheduled for Sunday.
