Ariana Grande has pulled out of performing at the Grammy Awards due to a disagreement with the show's producers which left her feeling "insulted", it has been reported.
The popstar had been scheduled to perform at the February 10 show, but as well as not taking to the stage, she reportedly won't even attend this year's ceremony.
A source told entertainment trade publication Variety that Grande felt "insulted" after producers initially refused to let her perform her latest single, 7 Rings.
The producers then allowed Grande to perform the track as part of a medley, but insisted the second song be of their choosing. Grande is said to have pulled out of performing at this stage.
The source added that stipulations such as these were not imposed on other performers on the show.
Grande is nominated for two Grammys this year, Best Pop Vocal Performance for God Is a Woman and Best Pop Vocal Album for Sweetener.
Other acts set to perform at this year's Grammys include Katy Perry, Miley Cyrus, Cardi B, Diana Ross, Shawn Mendes and Camila Cabello.
