TMZ has learned that Paris Hilton and Shanna Moakler have both filed police reports early Wednesday morning, alleging each attacked the other.

Elliot Mintz, Paris' publicist, tells TMZ that his client was at Hyde nightclub Wednesday night and at approximately 1:10 a.m. she says she was approached by Shanna, who allegedly began screaming obscenities at her. Hilton says at that point Moakler struck her in the jaw with a closed fist as she continued to shout profanities. Mintz says Moakler was restrained and several people helped Paris exit Hyde. Mintz says Hilton never touched Moakler.

Mintz and Hilton 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.

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 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.
