Ariana Grande called Grammys producer Ken Ehrlich for lying about the reasons for his absence from this weekend's awards.
Ehrlich had told the Associated Press that Grande was in talks to perform at the Grammy on Sunday, but in the end "felt that it was too late for her to put something together".
Grande has publicly contested that the lack of time was the decisive factor, tweeting"I kept my mouth shut, but now you're lying about me."
"I can put together a performance during the night and you know it, Ken," he continued. "It was when my creativity and personal expression were stifled by you, that I decided not to participate, I hope the show is exactly what you want it to be and more."
The singer went further, stating that "she offered 3 different songs: it's about collaboration, it's about feeling supported, it's about art and honesty, not politics, not doing favors or playing games. a game for you .. and I'm sorry but that's not what music is for me. "
Grande is vying for two awards on Sunday: the best pop solo performance for God Is A Woman, and the best pop vocal record for Sweetener. There is no participation in the ceremony, although he tweeted that he is "still grateful for the recognition of this year".
His absence will be a blow to the Grammys, which they described in the advertisement – Grande tweeted that "he passed a Grammys bus with my face" – for a show whose rating fell to historic lows last year.
The dissident tweets come after a Variety report that Grande felt "insulted" when Grammys producers did not allow her to perform in 7 Rings, the most famous single of her album thanks, which falls on Friday, two days before the broadcast. The producers would have consented to 7 rings only if performed as part of a medley, but Grande pulled back when they insisted on choosing the second song. Variety's source claimed that no other interpreter responded to these requests.
A similar problem occurred last year when Lordina, who received multiple nominations, refused to perform after being offered a seat in a tribute to Tom Petty instead of in a solo sequence. At the time, Ehrlich said, "We have a box and it fills in. You had a great album, there's no way you can really deal with everyone."
Grande remains one of the biggest pop stars in the world, with 144 million followers on Instagram and 60 million on Twitter. When 7 Rings was released last month, it broke the Spotify record for most of the games in a 24 hour period with 15m streams.
The ceremony of this year will see performances by Lady Gaga, Miley Cyrus and Diana Ross with the nominations led by Kendrick Lamar.
