Grande is said to have pulled out of performing at this stage.
First, Grande, 25, shared a screenshot of an Associated Press story in which Ehrlich said Grande, after a month of negotiating, "felt it was too late for her to pull something together" for the show, which is broadcast live Sunday in L.A.
Grammy producers faced a similar situation with Lorde before last year's ceremony, when they wouldn't let her perform a song from her album Melodrama, which was up for Album of the Year.
She's also sure to be hoping for success at the music awards - as she's up for five gongs.
The producers then allowed Grande to perform the track as part of a medley, but insisted the second song be of their choosing.
Complicating matters, the show had been promoting Grande as a performer on social media. The singles from the album, "No Tears Left to Cry" and "God Is a Woman" were dropped throughout the spring and summer, during a time in which Grande was constantly in the new for her relationship with Davidson. Understandably, Grande felt "insulted" and informed the Grammys to delete her invitation. The song is the second track from her new album "thank u, next" expected to be released February 8 before the awards show.
