Hilary Duff’s neighbor apparently called the NYPD, claiming that her boyfriend punched him over his chain smoking.

“I had to call the police this morning because Hilary’s boyfriend, Matthew Koma, barged in and tried to punch me in the face,” Dieter Addison, her neighbor, said to Page Six. “I tried to avoid his fist, but he hit me on the head. So I pushed him out of the apartment, but I didn’t assault him.”

Cops came to her Soho apartment building. “I have studied martial arts for many years, and I know how to block people,” the neighbor explained. “I didn’t want a fight. I immediately called my lawyer who told me to call the police.”

Hilary’s people didn’t comment on the attack, but they did confirm they’re pissed at Matthew’s smoking: “Hilary and her young son have been subjected to excessive secondhand smoke, latenight noise, garbage in the hallways, and an overall hazardous living environment from this man for months now,” her reps said. “She tried numerous times in polite ways to handle this situation including countless sessions with the landlords of the building. As every mother knows, protecting your kid has to come first and foremost and that is her primary goal. She reached a breaking point after a 15 hour work day and yet another sleepless night.”
