Ariana Grande is speaking out after a Grammys producer said the singer wasn't performing at the Sunday night show because she "felt it was too late for her to pull something together."

After Grammys producer Ken Ehrlich told The Associated Press that Grande said it was too late for her to adequately prepare, Grande refuted that claim on social media.

After sharing a screenshot of an article including Ehrlich's comments, Grande wrote on Twitter: "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."

She continued: "i 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. it’s just a game y’all.. and i’m sorry but that’s not what music is to me."

The 2019 Grammys will broadcast live from Los Angeles' Staples Center Sunday on CBS at 8 EST/5 PST. Ehrlich told the New York Times that Drake, Kendrick Lamar and Childish Gambino all declined offers to perform in the show.

In Ehrlich's AP chat, he said the show had multiple conversations with Grande about the possibility of appearing. He said the Recording Academy wanted her to perform after having "conversations over the past month or so" and by the time it seemed like a performance might work out, Grande said it was too late to prepare.

Variety reported this week that the singer had a disagreement with Grammy producers on which songs she would perform, so she pulled out.

Grande is nominated for two awards and said she's "still grateful for the acknowledgement this year," though she didn't receive the number of Grammy nominations many fans hoped, with her "Sweetener" album snubbed in the night's biggest categories.

The last time Grande attended the Grammys was in 2016, skipping the 2017 awards despite receiving two nominations. She wasn't nominated for any awards in 2018.

Grande does have an album dropping Grammys weekend, with "Thank U, Next" arriving Friday.

Grande has been featured on billboards promoting Sunday's show, and the irony wasn't lost on the singer as she was ranting on Twitter about her decision not to perform being miscast – noting that she passed a bus sporting a Grammys ad with her face as she was typing.

The pop star's mother, Joan Grande, also chimed in on Twitter.

"I agree with you Ariana," she said, and called the Grammys ad campaign "exploitive" for featuring her daughter's face even though she was never a confirmed performer.
