Ariana Grande is clapping back at the producer of the Grammys for 'lying' about why she isn't performing at the awards.

Ariana Grande has opened up about why she cancelled her performance at Sunday's Grammy awards.

She also responded to a recent interview that the show's producer, Ken Ehrlich, gave to The Associated Press. In it, he claimed that the pop star "felt it was too late for her to pull something together."

Ehrlich said that the Recording Academy was hopeful that Grande would take the stage after having "conversations over the past month or so." The producer added that Grande's choice to pull out of the show is "too bad" because she's a "great artist."

He also said that he'd still "love to get her in the show this year."

Grande, who has been nominated for two awards at the ceremony, said Ehrlich was 'lying' about what happened.

Taking to Twitter, she wrote:

"I’ve kept my mouth shut but now you’re lying about me. I can pull together a performance over night and you know that, Ken. It was when my creativity & self expression was stifled by you, that I decided not to attend. I hope the show is exactly what you want it to be and more."

Grande later tweeted that she "offered 3 different songs." She explained, "It's about collaboration. It's about feeling supported. It's about art and honesty. Not politics. Not doing favors or playing games."

She concluded: "It's just a game y'all…and I'm sorry but that's not what music is to me."

The 2019 Grammys, hosted by Alicia Keys, take place this Sunday, February 10th.
