Every so often, Ari might post a special tribute, photo or video of Mac Miller on her social media, all with a touching message.
Most recently, she posted a throwback from Thanksgiving last year, writing that he was very missed.
But, as trolls go, they had something horrible to say online.
"She milkin this shit bruh," a person wrote on Twitter.
Tweeting that person back directly, Ariana wrote, "i pray you never have to deal with anything like this ever and i’m sending you peace and love."
Haters gonna hate.
