Ariana Grande is done caring about her exes--except one.

The Sweetener singer paid tribute to her late ex-boyfriend Mac Miller last night (Nov. 9), tweeting lyrics from his song "Cinderella" that echo how she feels about this loss. "U in my dreams that’s why I sleep all the time,” tweeted Grande.

Earlier this year, Grande revealed the steamy love song song was written about her, but now the song has taken on new meaning for her. Since his passing, she has often mentioned how much she misses him.

A couple of days before tweeting the "Cinderella" lyrics, a fan tweeted to Grande a video of Miller listening to her Sweetener song "R.E.M." in an Instagram live video before the album's release. Grande replied, writing "he is supposed to be here,” then thanking the fan for finding it.

Grande shared an incredible bond with Miller, but his substance abuse was the catalyst for their breakup, with Grande tweeting "pls take care of yourself" after Miller was arrested for driving under the influence shortly after their breakup.

Grande also showed that she still deeply cares about Miller in her hit new breakup song "Thank U Next," singing "Wish I could say 'Thank you' to Malcolm/'Cause he was an angel." This week, the Los Angeles County Coroner's officer revealed that Miller's cause of death was a "mixed drug toxicity."

Despite  their relationship being far from perfect, he will always be one of Grande's most beloved exes.
