A Bitcoin businessman's phone records reveal he was in the area on the morning a PR guru's office was graffitied with the 'Roxy's a c**t', a court has heard.
Sweaty Betty founder Roxy Jacenko stepped into the witness box in a Sydney court on Thursday, seeking an apprehended violence order against Anthony Hess.
Ms Jacenko believes the Melbourne man was behind the attack on her Paddington office earlier this year and says the incident has left her fearing for her safety.
She claims the vandalism was revenge, after she and Mr Hess got into an argument after one of her $500-a-head 'Conversations' events at the Ivy in February.
The Downing Centre Local Court heard on Thursday the pair first met when Mr Hess allegedly began 'shouting' at Ms Jacenko when she was about to walk on stage.
Mr Hess today came face-to-face with his alleged nemesis Ms Jacenko, who was dressed in a $1500 Valentino dress and $1100 shoes.
He was accompanied by a friend who used a $4000 Fendi monster bag to hide her face from news cameras.

In court today, Ms Jacenko told the magistrate: 'He was in my face shouting,' describing it as 'screaming, ranting.'
The argument came after Mr Hess got into an stoush with two women at Ms Jacenko's event.
One of those women claimed in court that Mr Hess called them 'bush pigs', leading to Ms Jacenko's staff and later the PR maven herself to ask him to leave.
Two months after that alleged encounter, Ms Jacenko's Paddington office was vandalised one night with the words 'Roxy is a c**t'.
Ms Jacenko's lawyer, a former NSW Supreme Court judge, said Mr Hess's phone records put him in the vicinity of her office the night that graffiti was written.
The words 'Roxy Jacenko is a crook' were also scrawled on a traffic barrier on nearby Syd Einfeld Drive.
Greg James QC told the court in his opening address that Mr Hess had 'no alibi for the night', but had the 'opportunity, the motive and the means' to target his client.
Mr James said Ms Jacenko's evidence included Instagram screenshots and CCTV footage of the alleged attack showing the vandal's 'clothes and size ... all of which are consistent with the defendants' clothes, size and attempts at concealment'.
'The vandalism was plainly designed to intimidate and to affect (Ms Jacenko's) reputation within the community,' Mr James said.
He said telephone records 'placed him (Mr Hess) in the vicinity of the general area where the vandalism occurred'.
Ms Jacenko claimed the incidents had left her fearful, telling the court she felt 'shaky', and that she had to tell her child's primary carer 'to be very alert'.
But there were fireworks inside the courtroom between Ms Jacenko and Mr Hess's own
