Over the weekend, The Mac Miller estate released his final, posthumous album Circles. The album is a counterpart to his last album, Swimming, and is another quality body of work from the Pittsburgh artist. One of the tracks, 'I Can See' has many people talking about who exactly is singing melodies on the hook. Ariana Grande fans believe it's her but she has yet to confirm or deny the rumor. I will say it definitely could be her harmonizing in the background and it obviously makes sense for her to be on some part of the album. Hit the video below and skip to 1:06 for the vocals in question.
