Mourning Miller's death, Grande shared a black and white picture of the late rapper without a caption.
The pop stars dated for two-and-a-half years before ending their relationship in the spring of 2018, confirmed The Hollywood Reporter.
Miller had opened up about their relationship during an interview on Beats 1 on Apple Music in July and said that both he and Grande had moved on.
The 26-year-old passed away on September 7 after an alleged drug overdose in California.
