In a series of videos and pictures, Duff lamented to her 9.2 million followers that her "a--e neighbor ... smokes cigarettes and weed all night long", and that her apartment stinks because of it.
The Younger star used Instagram Wednesday morning to publicly shame her neighbor for smoking, explaining that neighbor Dieter Addison's behavior was affecting her daily life. My neighbor smokes cigarettes and weed all night long. "Seriously, what do I do?" she added. "Must be nice. Have some respect for your neighbours who work hard to live in that building. Don't be a dick dude-and put your trash down the shoot [sic]".
Duff identified the man as Dieter Addison who is the grandson of wealthy German-born beer importer H Dieter Holterbosch, according to Page Six.
Duff later shared a screenshot of Addison's Instagram account, which was set to private.
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.
'When they moved in I turned down the music right away, ' he said. Holterbosch also imported Lowenbrau beer to NY state, at which time he developed a large beer distribution network to include other brands. He did admit that he does smoke cigarettes and has received complaints about the cigarette smoke from Duff. Hilary Duff doesn't consider herself to be a confrontational person, but, as a mom to 6-year-old Luca, she isn't hesitant about letting her "inner Mama Bear" out. "But the building owners did not get back to me to give the okay for the work to be done, but I did try".
Before she signed off, Duff slung a few more jabs at her neighbor, who she accused of "breaking all your furniture when you fight with your girlfriend or boyfriend".
Mr Addison also denied being unemployed, telling Page Six he is employed at his family's real estate office.
She then quickly followed up the first video with a much more personal dragging of Addison. Then Duff chose to try and use what information she had about this guy to track him down on social media.
The smell of her neighbor's smoking has now invaded Duff's apartment and caused her to have very strong feelings about his lifestyle.
