RnB star Usher has reassured shocked fans that he is still very much alive following hoax death reports claiming that he had died in a car crash on Tuesday.

The Climax singer quickly headed to Twitter to post snaps of himself after hearing the news of his sudden demise.

Taking it in his stride the 33-year-old singer included caption such as: "Never Scared, Never Dead. Just #Lookin 4 myself", "Livin' Legend" and "I must've died and went to heaven...Alive and cold kickin ass!"

According to Global Associated News, he had died in a single-vehicle crash while driving over 95 miles per hour on route 80 in Georgia.

"Usher was pronounced dead at the scene by paramedics responding to the accident and was identified by photo ID found on his body. Alcohol and drugs do not appear to have been a factor in this accident," the site said.

"Highway safety investigators told reporters that Usher lost control while driving a friend's vehicle on Interstate 80 and rolled the vehicle several times killing him instantly."

Usher's outraged ex-wife Tameka Raymond took to Twitter to vent her anger: "I don't play the death rumour games. That almost killed me."

Usher is the latest celebrity to figure in hoax reports about his death. Charlie Sheen, Jon Bon Jovi, Rihanna and Spanish film director Pedro Almodovar have all had premature deaths announced online.
