Former X Factor star Nathaniel O’Brien has died tragically in a car crash.
The popular singer starred on the Australian version of the X Factor last year.
Nathaniel had been performed at the Burra Country Music Festival, South Australia and was travelling to Adelaide as he was due to perform at the Tea Tree Gully Hotel that night.
According to Australian Police, he died after his car hit a tree around 11am on Sunday morning - he was the only person travelling in the vehicle.
He died at the scene.
Australian singer Natalie Bassingthwaighte, who was O'Brien's mentor on the reality singing show, tweeted a tribute as soon as she heard the tragic news.
