The rumours originally started via a BBM message that stated that Joost had died at 17:45 on Tuesday night.
On 12 May 2011, Van der Westhuizen's publicist announced that he had a muscle related neural disease, believed to be a form of motor neurone disease.
Joost’s J9 foundation denied rumours that Joost had passed away. “Confirming that the BBM message about Joost is false. He is at home enjoying a relaxed evening,” they wrote on their Facebook page.
Joost himself later tweeted; “Alive and kicking folks! Ignore the rumours.”
YOU Magazine spoke to Joost this morning and he assured us that he was doing fine.
