Paris Hilton and publicist, Elliot Mintz then went to the LAPD's Hollywood Division, where she filed a police report, alleging battery.
We're told Moakler also went to the station to file a report against Paris' companion that evening, Stavros Niarchos, alleging that he poured a drink over her head. A source tells TMZ that Moakler alleges that Niarchos shoved her down some stairs.
We're told police took photos of both women at the station, though it's unclear if either showed visible signs of injury.
Mintz told TMZ, "I would encourage Paris, with the consent of her attorney, to seek a restraining order against Moakler to prevent any escalation of this irrational and dangerous behavior."
We're told some of the dancers from "Dancing with the Stars" witnessed the incident. Moakler was a contestant on the show but has already been eliminated from the competition.
