Grande apparently meant to perform her new single "7 Rings" at the 61st annual ceremony, which has advertised her appearance far and wide in the weeks leading up to the show, but she felt "insulted" when producers refused to let her play the song, unnamed sources told the outlet.
The singer and producers at first reached a compromise, agreeing that 7 Rings would be part of a medley that Grande was to perform.
A source close to the situation stated that these preconditions weren't enforced on any of the other performers - like Cardi B, Shawn Mendes and Miley Cyrus.
The decision comes after Ariana was snubbed in all of the major categories, receiving only nominations for best pop vocal performance for God Is a Woman and best pop vocal album for Sweetener. "I want to do it on my own terms from now on", Ariana told Billboard for her "Woman of the Year" cover story in December 2018. They instead offered her a spot during the Tom Petty tribute, which she declined. "I don't want to do what people tell me to do, I don't want to conform to the pop star agenda".
Her 7 Rings song is the latest single from her new album Thank U, Next, which will be released on Friday, just two days before the Grammy's air from the Staples Center.
