Duff said she returned home from a 15-hour workday, but got no sleep that night because of the neighbor's antics.
Duff, 30, took to social media to issue a plea to her fellow New Yorkers for advice on how to deal with a hard neighbour in her exclusive Soho apartment building. "Umm.my apartment reeks. Seriously, what do I do?"
In a second clip, Duff continued: "We know your parents pay your rent, we know you've never worked a day in your life. And put your trash down the shoot".
"I live with a sober companion, I've been sober for months now".
Along with plastering her neighbor's name (Dieter Addison) all over each of her Instagram posts, Duff also drew cat faces over a blurry picture of him - which honestly feels a little middle school to us.
"I am getting a lot of hate mail and threats from her fans, it is so bad I'm going to have to get a bodyguard", Addison ("the neighbor") told Page Six.
Dieter spoke to the website by phone, saying that he doesn't smoke pot and he actually lives full-time with a sober companion. Holterbosch also imported Lowenbrau beer to NY state, at which time he developed a large beer distribution network to include other brands.
Hilary went on to troll Addison after pulling up the front page of his private Instagram account.
He said the problems started immediately after Hilary and her singer beau Mathew Koma moved in next door in January. And well, I'll just let you behold them for yourself.
He is the grandson of H. Dieter Holterbosch, a German immigrant who came to America and became a self-made man who built a business empire that included a family vineyard, importing Lowenbrau beer to NY and starting a distribution network for other beers. "But the building owners did not get back to me to give the okay for the work to be done, but I did try".
While Duff concluded the rant by advising Mr. Addison to "get a vape" and go to therapy rather than breaking furniture whenever he fights with his significant other, our anonymous source assures us that Addison is simply a social butterfly who happens to throw a late-night after-party (or two) every once in a while.
She then quickly followed up the first video with a much more personal dragging of Addison.
