Miller, a Point Breeze native, was found dead in his California home from a suspected overdose on September 7.
Last Friday, the Los Angeles County Department of Medical Examiner-Coroner confirmed in a statement to Fox News that Miller was found unresponsive in his Studio City, Calif. home, and was pronounced dead at the scene at 11:51 a.m.
She's now posted a video with a lengthier tribute, writing: 'I adored you from the day I met you when I was nineteen and I always will. She spoke about her love for Mac and added that they had talked about him overdosing "so many times". So many times. I'm so mad, I'm so sad I don't know what to do. Among those was Ariana Grande, who was in a longterm relationship with Miller until earlier this year. I really wanted to.
Miller's friend, Shane Powers, has said that there was "no one in his life more ready to go to the wall for him" than Grande. The kindest, sweetest soul with demons he never deserved.
Ariana has stayed silent since Mac's death, though she shared a caption-less picture of him days after it was announced. The video appears to have be filmed during an intimate dinner Ari and Mac enjoyed while they were still together.
