Paris Hilton's animosity with "Dancing With the Stars" ejectee Shanna Moakler allegedly escalated into physical violence while the two were out partying.
The hotel heiress filed a police report with the LAPD's Hollywood division claiming that she was attacked by Moakler last night, reports TMZ.com.
In a video on the celebrity gossip site, Hilton's publicist Elliot Mintz explains that his client was at Hyde nightclub at around 1 a.m. Wednesday (Oct. 4) when "[Moakler] struck Paris in her jaw with a closed fist. Paris was hit. She immediately exited the club through the back door.
"Paris told me it was a completely out-of-the-blue and without any provocation whatsoever, and in fact, while the alleged battery was taking place, Shanna was shouting all kinds of foul words at her and appeared to be completely out of control. That is what's being alleged in the complaint."
Although Hilton didn't need medical attention, she decided to report the incident to the police.
"If someone walks up to you and without provocation punches you in the face," says Mintz, "I think it's a very wise idea to go to the police and report the action and possibly even consider, with the approval of her attorneys, the issuance of some kind of restraining order because that kind of conduct simply cannot be tolerated for any reason at any time at any place."
Evidently, Moakler filed a police report of her own -- not against the celebutante, but against Hilton's ex Stavros Niarchos.
"It was my understanding that Shanna has filed her own complaint against Stavros alleging that he poured a drink over her head or something to that effect," says Mintz. "You'd have to ask her about that."
TMZ also reports that Niarchos allegedly pushed Moakler down some stairs.
Tabloids have speculated that the bad blood stems from Hilton's rather close friendship with Blink 182 drummer Travis Barker, who filed for divorce from Moakler in August. Hilton and Barker were seen snogging in a Manhattan club in September.
Moakler is a former beauty queen who was previously married to Oscar De La Hoya. She has two children with Barker. Moakler was a contestant on "Dancing With the Stars" this season, but already got the boot.
Hilton has been visiting the police a lot lately. In September she was arrested for drunk driving, which led to being charged with driving under the influence and driving with a blood-alcohol level of .08. She claims that she didn't have anything to eat that day, but drank one margarita.
