A cheating husband told his mistress he was separating from his wife before his spouse allegedly ran them over, a court has heard.
Christie Lee Kennedy, 37, had been married to David Larkin for almost a decade when she discovered he was having an affair in March 2021.
The mother-of-two allegedly then got into her BMW SUV, tracked down Mr Larkin in Brisbane's north using a phone locator app, and hit him and Zowie Noring.
Kennedy next got out of her car, grabbed Ms Noring by the hair and repeatedly punched her in the head while screaming obscenities, the District Court was told.
The jury on Tuesday was shown CCTV footage from a nearby home of the incident at Wavell Heights.
Ms Noring told the court that she had been intimate "only once" with Mr Larkin, a week before the incident.
However, Ms Noring said Mr Larkin had told her he was "in the process" of separating from Kennedy and she believed the couple had split by the time of the incident.
The next time she saw Mr Larkin after they had sex was when they met at Wavell Heights and were hit by the car, Ms Noring said.
She "blacked out" after being struck but could recall being held by the hair and punched multiple times by Kennedy after regaining consciousness, she said.
"I was being called, forgive my French, 'you're a f***ing fat moll'," Ms Noring said.
"After the punching had ceased ... I saw David lying on the road with his arm out, almost like he was reaching for me."
Ms Noring said she got in her car and left the scene because she was "extremely afraid" of being attacked again.
She suffered cuts and bruising, fearing the worst when the back of her head felt "squishy".
"I remember ... thinking ... 'probably shouldn't have touched that, it could be my brain'," Ms Noring said.
Defence barrister Penny White earlier suggested to Mr Larkin that Kennedy asked if he was OK after the incident as he lay on the road.
"You said 'yes, I can't believe you just did that to me'," Ms White said.
"She said 'I am sorry but I can't believe that you did that to me either'."
Mr Larkin said the interaction "possibly" happened.
"I had just been hit by a car, I can't be sure," he said.
Mr Larkin said there had been "aggression in the past" from his wife.
Years earlier she hit him in the back of the head and ripped his shirt off during an argument, he said.
But Ms White suggested Kennedy was the only one who was injured during the argument, suffering a rolled ankle.
"You are doing everything you can I would suggest to paint yourself as a victim here and my client as the aggressor," she said.
Ms White also took Mr Larkin to task about telling a hospital social worker after he was hit by the car that he was just friends with Ms Noring.
"I believe you would interpret that as being a lie, I guess," Mr Larkin said.
Kennedy has pleaded not guilty to two counts of malicious acts with intent to disable.
She has pleaded guilty to unlawful assault.
The trial before Judge Tony Moynihan continues.
