Miller, who died in September last year, was nominated in the Best Rap Album category for Swimming. Cardi B ended up winning the award for her record Invasion of Privacy.
Grande, who used to date Miller, shared her dismay on social media in now-deleted tweets, writing according to screenshots: “trash”, “f***”, and “literal bulls***”.
She then clarified that her comments weren’t a reflection of her feelings vis-à-vis of Cardi B, but rather an expression of her profound disppointment on Miller’s behalf.
“Nothing to do w her. Good for her. I promise. I’m sorry,” she wrote in a message that also appears to have been deleted.
Grande added of Miller: “He slept in the studio for two months.”
In another tweet, she referred to his mother Karen, saying she was going to have “a green suit made”, presumably in preparation for the ceremony.
Swimming was released in August 2018, a month prior to Miller's death.
