Dua attended the grammys for album of the year for "Future Nostalgia "
She is a very known artist right now and is at her biggest. But lost album of the year to grande you can see her eye roll as the word" ar" came out the mouth of Celion.
She is a new artist and may of felt rowdy after deaft she may of filled up with anger and took her anger out on Grande.
She can be quite rude as she has sued spotify after using james Charles picture instead of hers because they look so similar so she could of easily killed Grande and blame Charles.
