The 31-year-old Australian football star was filmed drunkenly calling PC Lovell ‘f****** stupid and white’ in the early hours of January 30, 2023.
The court heard how Kerr and her now fiancée, Kristie Mewis, who is also a footballer for West Ham and the USA, believed they had been kidnapped by a taxi driver after a night out, culminating in Mewis kicking out the taxi window in a bid to escape the vehicle.
The driver reportedly told police that the two footballers had refused to cover the cost of the clean-up and damages.
At the police station, Kerr was alleged to have become 'abusive and insulting' towards PC Lovell.
A jury at Kingston Crown Court took just over four hours to return a unanimous not guilty verdict.
Kerr, who was wearing a white zip-up shirt and black trousers, emerged from the dock with a smile on her face, while Mewis broke down in tears.
In a parting statement, Judge Peter Lodder said: ‘Take the view her own behaviour contributed significantly to the bringing of this allegation and has a significant bearing on the question of costs.
‘She herself has to accept by virtue of video recording.’
Kerr, who has not played since rupturing her ACL in January last year, told a court last week that she called a policeman 'stupid and white' because he didn't understand his privilege and treated her differently because of the colour of her skin.
Kerr said PC Lovell failed to listen to her and fiancée Kristie Mewis when they told him they believed a taxi driver had tried to abduct them.
The Australian captain made the comments when the cab driver took them to a police station after she vomited out of his window following a night out.
Kerr said the driver began to 'drive dangerously' after she was sick, leaving the pair distressed - and making her think of the abduction and murder of Sarah Everard in March 2021. They kicked out the rear window in a bid to escape.
The cabbie rang the police and drove to Twickenham Police Station, where he was met by PC Lovell and a colleague, who arrived at the station at the same time in a marked car.
