Barker, the drummer for Blink-182, filed for divorce in August from Moakler, a former beauty queen who was recently voted off "Dancing With the Stars." In September, Barker was apparently videotaped kissing Hilton, who needs no introduction.
Then Hilton encountered Moakler at the Hyde club in Hollywood last night. The following reenactment is based on reports by police, publicists for both women, but unfortunately no pugilistic experts:
Hilton says Moakler walked up to her, "used the most vile of language" and then punched her in her jaw.
Moakler contends she exchanged mere profanities with Hilton, at which point Hilton's ex-boyfriend Stavros Niarchos emerged from the entourage, bent Moakler's wrists, poured a drink on her and shoved her down some stairs.
Hilton, 25, and Moakler, 31, both filed police reports alleging battery. Officer Karen Smith said police took pictures of Moakler and Hilton at the station, and that police planned to speak with witnesses at the club as part of their investigation.
Moakler and the tattooed punk rocker Barker were an unlikely pair when they married in 2004, documenting their lavish wedding and life on the MTV reality show "Meet the Barkers." They had two children. Moakler also has a 7-year-old daughter with boxer Oscar De La Hoya.
TMZ.com posted what it said was video of Barker and Hilton making out in a New York nightclub last month. But Hilton's publicist, Elliot Mintz, said the two are "just friends."
