He was once best known for being a hugely talented American football player – still holding many records today.
But over the years O.J Simpson’s personal life took over and various scandals have become bigger than his various sporting achievements.
We take a look back at the moments which have rocked his world – and that of those around him.
The murder of Nicole Simpson
On June 12 1994 Nicole Simpson and her friend Ronald Goldman were found stabbed to death outside her home.
O.J was charged with their death but controversially he was acquitted of murdering them in the case dubbed the ‘Trial of the Century’.
One leather glove was found at the crime scene – which was famously too small for O.J.
“If it doesn’t fit, you must acquit” became his lawyers mantra throughout the case.
Two years later though, O.J lost the civil wrongful death lawsuit brought by Mr Goldman’s family which ordered him to pay them £21 million in compensation.
The Armed Robbery
In 2007 a group of men, headed up by Simpson stormed the Palace Station hotel-casino and took sports memorabilia at gunpoint.
Simpson admitted to taking the items, which he said had been stolen from him, but denied breaking into the hotel room; he also denied that he or anyone else carried a gun.
He is currently serving up to 33 years in prison for armed robbery for the incident.
The truth about Khloe Kardashian
Over the years there has been much speculation that O.J could be the father of Khloe Kardashian .
Her mum Kris was very close to Nicole Simpson at the time of her death and O.J was a big part of their family.
However O.J has shut down claims once and for all that he is her father, according to a prison guard.
According to the now-retired prison guard, O.J. opened up about rumours he had an affair with Kris and told him: “I would never do that to my friend Bob. I would never tap Kris.”
A love affair with a transsexual prison mate
A transsexual former prisoner claims to have had sex with O.J. Simpson while in prison.
Former prostitute Jazmena Jameson – who has since revealed she is HIV positive – said the pair flirted for many months before becoming intimate.
She said she seduced Simpson, who was nicknamed The Juice, while inside his cell and ended up performing oral sex on him.
