Rihanna and Stormzy are among the stars mourning Linkin Park's Chester Bennington who has died, aged 41.
The Los Angeles County Coroner's office confirmed the death and said the singer had apparently hanged himself.
Chester's bandmate and friend, Mike Shinoda, tweeted that he was "shocked and heartbroken".
The band's debut Hybrid Theory remains one of the biggest selling albums of the millennium.
Last night they posted a photo of the singer, surrounded by fans.
Tributes to the singer from across the musical spectrum have been paid on social media.
Linkin Park's co-founder Mike Shinoda said an official statement from the band would be released soon.
