Ehrlich told the AP that Grande "felt it was too late for her to pull something together". Grande was quick to refute this account on Twitter, her chosen medium for handling such matters. "I'm in tears with honor and gratitude..." she tweeted after her win for A Star Is Born was announced. "I hope you do, dad". She ended the tweet with her trademark black heart emoji.
Carlile told the AP she stands behind Grande's "decision to stand up for herself and her art".
Meanwhile, Keys had talked about the hosting duties last month.
In the pre-gala ceremony in Los Angeles, at which most of the more than 80 prizes are handed out, folk rocker Carlile - this year's most nominated woman - won her first 3 Grammys ever, in the Americana and American Roots categories. And, well, let's just say there aren't a lot of "who is Drake" and "who is Kendrick Lamar" articles being written for tonight.
It was at this point that the Grammys cut off Drake's microphone and went to commercials. In 1989, Will Smith and DJ Jazzy Jeff boycotted the show after they learned that the presentation of the best rap performance award wouldn't be televised, according to The Hollywood Reporter. "Shallow" is still up in three other categories, including Record of the Year. I'm so excited to be the master of ceremonies on the biggest night in music and celebrate the creativity, power and magic.
Drake, Lamar and Childish Gambino - the rap alter-ego of actor Donald Glover - have also all turned down performance offers, and it was not clear if they would even attend.
The Grammys have also struggled with gender inequality, an issue that came to its head past year.
Janelle Monae remembers being frustrated at last year's Grammy Awards, where male acts dominated in nominations and the only woman competing for the night's top award, Lorde, didn't get a chance to perform onstage. Taylor Swift, who was snubbed and one scored one nomination, also won't be at the show. He later acknowledged that it was a "poor choice of words", and his much-criticized remarks forced the academy to launch a new task force focused on inclusion and diversity.
Stuff will be live blogging Monday afternoon's Grammy Awards, starting with the red carpet action from midday.
