Katie Price reveals details around Oscar Pistorius messages during his trial WATCH! British TV personality Katie Price has given more details on the messages she claims to have received from Oscar Pistorius during his trial.
"We are aware of the lucrative mini-industry of paid-for interviews and bought information that developed around this case, and we wanted to steer very clear of this. Despite Oscar’s crippling legal fees, this remains our position. Neither Oscar, nor the Pistorius family will make any money out of this documentary. Any (potential) proceeds would go to charities for children. "
