On what would have been Miller's 27th birthday, Grande tweeted out a simple message, without directing it at anyone in particular.
"miss u," she wrote.
"I adored you from the day I met you when I was nineteen and I always will," she captioned a video of Miller in the week following his death. "I can’t believe you aren’t here anymore. I really can’t wrap my head around it. We talked about this. So many times. I’m so mad, I’m so sad I don’t know what to do. You were my dearest friend. For so long. Above anything else. I’m so sorry I couldn’t fix or take your pain away...I hope you’re okay now. rest."
Grande, who suffered through a broken engagement and the death of Miller in 2018, posted a year-end Instagram that noted how tough the year was for her.
