The 25-year-old singer has reportedly pulled out of performing at the Grammy awards following a dispute with producers.
Sources told Variety that Ariana Grande felt "insulted" when producers wouldn't allow her to perform her latest single '7 Rings' at Los Angeles' Staples Centre but a compromise was reached where the track would be part of a medley.
However, when the organisers insisted they would be choosing her second song, she pulled out, with the insider explaining no similar restrictions had been placed on any of the evening's other performers.
Ariana is nominated for Best Pop Vocal Performance.
