"Cinderella" happens to be the name of a song the late rapper wrote about her.
“Daddy told you, better bring your ass home/ Cinderella better get your ass home” Miller raps on the track, and later, “Ooh Cinderella don’t you run out of time/ It feels like you’ve been taking all day/ Wherever you came from, wherever you going/ I promise I’m not far behind.”
Mac Miller was honoured on the night during the 'In Memoriam' segment, however, Ariana went OFF on Twitter when he lost his nomination of Best Album to Cardi B.
