According to the Academy, the best new artist grammy is "For a new artist who releases, during the Eligibility Year, the first recording which establishes the public identity of that artist" I guess the Academy doesn't consider releasing two top 10 multi-platinum singles, a third platinum single, and a platinum album as establishing Alessia's public identify. It must be her featured vocals on other artist's records which established her public identity.
Nevertheless, Alessia took to instagram to play the victim for people pointing out the simple fact that Alessia, with her platinum album and platinum singles from three years ago is not a new artist. Somehow, she's making this about her prior self-esteem issues. I'll pass on feeling bad and reiterate that you are not a new artist and someone dropped the ball on this one. It's very simple #facts!
