Longoria claimed the officer's behavior was improper when he pulled her and San Antonio Spurs star Parker over for impeding traffic last week.
Longoria's publicist could not confirm the report — carried on an entertainment news website yesterday — that the "Desperate Housewives" star was preparing to file a formal complaint with the San Antonio police.
Officials at the police department said it had no record of a complaint yesterday.
During the confrontation in San Antonio, where they live, police say, Longoria — who is of Mexican ancestry — shouted an expletive at the officer and referred to him as "just a Mexican bike cop."
The incident started around 12:45 a.m. last Saturday, when the bicycle-riding cop waved a flashlight at Parker, to motion for him to stop blocking traffic, the police report says.
The report says Longoria, 30, and Parker, 23, "began screaming in a verbally abusive and demeaning manner" after the cop pounded on the hood of the car with his palm.
"Well, [expletive] you then," reports quoted Longoria as saying to the cop.
As the officer was writing Parker a ticket for impeding traffic, Longoria allegedly snarled to her boyfriend: "He's just a Mexican bike cop. He only wants your autograph."
Longoria has insisted that she never made any racial remarks.
Parker is also said to have nearly hit a second cop with his car as he pulled away.
