At the station, Ms Kerr, her partner and Pc Lovell got into an exchange, described in court as a "heated argument", and Ms Kerr told police "this is a racial f****** thing".
Ms Kerr and her partner Ms Mewis told the court how they felt "dismissed" by Pc Lovell after explaining how they had been "trapped" in the back of a taxi and "held against our will".
During the trial, the court heard how Ms Kerr had accepted later calling Pc Lovell "stupid and white" during a heated exchange but denied that it amounted to the charge.
Ms Kerr, 31, and her partner, West Ham midfielder Kristie Mewis, had been out drinking when they were driven to Twickenham Police Station by a taxi driver who complained that they had refused to pay clean-up costs after one of them was sick and that one of them had smashed the vehicle's rear window.
At the police station, Ms Kerr became "abusive and insulting" towards Pc Lovell, calling him "f****** stupid and white".
