"She didn't directly kill him but she was the catalyst."
"I hope this messes her up."
"I'm not saying she's a murderer, I'm just saying she killed Mac."
Now, Miller's friend Shane Powers has countered these suggestions, setting the record straight in a recent podcast dedicated to his late friend in which he said there was 'no one in his life more ready to go to the wall for him' than Grande.
Recording an episode of The Shane Show, Powers said: "He had a lot of good stuff going on. Ariana and him were together, very much in love and I have to say she was incredible when he was first sobering up.
"She was a fucking G to him. There could not have been anybody more supportive of him being sober than Ariana. I saw that, I was around it, I took phone calls from her - 'How do I help?' 'What do I do?'
"This little girl was unbelievably involved and helpful to him being healthy. Because whether he's an addict or not, the way Mac partied was not healthy."
He continued: "I gotta tell you, man, there was no one in his life more ready to go to the wall for him when it came to him being sober and she was an unbelievably stabilising force in his life.
"She was deeply helpful and effective in keeping Mac sober and helping him get sober and she was all about him being healthy, period, in this area of his life."
Miller, real name Malcolm McCormick, was 26 when he died from a suspected overdose. The 'Self Care' singer was found at his home in San Fernando Valley, California, on 7 September.
Grande and Miller had previously dated for almost two years - shortly after the pair split, he was arrested for driving under the influence.
There was an element among Miller's fanbase who appeared to blame 25-year-old Grande for that incident and she took to Twitter in a bid to defend herself against the comments.
Now the 'One Last Time' singer, who paid tribute to Miller on Instagram days ago, has disabled comments on her posts because of a repetition of the trolling.
Her fans have fought back against comments, with one person taking to social media to post: "The amount of tweets blaming Ariana Grande for what happened to Mac Miller is disgusting, his addiction and lack of help is what drove this to happen, don't point the finger and blame."
Another added: "I hope Ariana has a strong support systems because the locals are intent on blaming her for something she has no business being blamed for... AGAIN."
