Twitter has spawned yet another false rumour of a celebrity death, that has Keshia Chante's mother saying it's all "a stupid and horrific hoax."

A rumour circulating on Twitter and Wikipedia Saturday claimed Chante, 21, had been in a serious car crash and was in critical condition in a Toronto hospital.

"Family and friends have been calling me all night in a panic," Chante's mother Tessa Agnelo wrote in an email to CTV.ca.

"I am happy to report she is fine."

Someone edited her Wikipedia entry to say a tractor trailer hit the R&B singer's vehicle on her way to a Toronto recording studio Friday night, and left her with critical injuries.

"My baby is safe, she was rear ended in May but is recovering nicely with the Grace of God," Agnelo wrote.

The Wikipedia entry claimed a Toronto newspaper had reported about the singer's injuries, but there was no such story on the newspaper's website.

Ontario Provincial Police Sgt. Graham Williamson told CTV.ca that the only Friday night crash involved a tractor trailer in Mississauga and a 17-year-old girl was the only person injured.

This isn't the first time false celebrity rumours have spread through Twitter.

In June, actor Jeff Goldblum went on The Colbert Report to confirm he was not, in fact, dead. A rumour had spread saying he fell to his death on a movie set in New Zealand, when he was in fact alive and well in Los Angeles at the time.
