And you thought you had shitty neighbors…

As we reported on Wednesday, Hilary Duff went on an EPIC Instagram rant against her apartment mate Dieter Addison because he allegedly smokes “cigarettes and weed all night long.”

That same day, Addison told Page Six that he was confronted by the Younger star’s boyfriend Matthew Koma, and things allegedly got physical!

He told the publication:

“I had to call the police this morning because Hilary’s boyfriend, Matthew Koma, barged in and tried to punch me in the face… 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.”

While Addison says he called 911 after the alleged fight, police sources say cops arrived at the Soho residence after receiving a complaint about someone smoking in a hallway.

“I have studied martial arts for many years, and I know how to block people… I didn’t want a fight. I immediately called my lawyer who told me to call the police.”

Addison eventually filed a police report with the First Precinct after NYPD officers noted his complaint at the scene.

In addition to assembling his legal team, Dieter — who says he’s been getting “a lot of hate mail and threats” — may file a restraining order against Duff and Koma.

“It is so bad I’m going to have to get a bodyguard.”

Although he claims his building is cigarette-friendly, Addison says he tried to work with Duff after she first complained about his smoke.

“When they moved in I turned down the music right away… When [Duff] first complained about smoke, I did offer to send in my own contractors to fix the ventilation problems. But the building owners did not get back to me to give the okay for the work to be done, but I did try.”

In response to Duff’s claims that his “parents pay [his] rent” and that he has “never worked a day in [his] life,” Dieter says he works at his family’s real estate office, and is an event producer who manages music artists.

In regards to the alleged incident, a rep for Koma said:

“These allegations are untrue.”

A rep for Duff told People that “there was no altercation whatsoever,” adding:

“Koma went over today and asked politely yet again for [the neighbor] to take his smoking outside so as not to impact others.”

The rep also elaborated on Hilary’s grievances against Addison:

“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… 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.”

Addison insists he does not smoke pot, and lives with sober companion Topes Calland.
