The popstar "Jessie j" was at the Grammys, to support some people , maybe she was jealous of Ariana. They did make a single in 2014 but after that Ariana's career took of.
Jessie has also been out of the spotlight for years now maybe killing ari would bring her back.
Jessie was caught leaving at half 9 , close to when ari left maybe she left a little bit later to make herself sound like she didnt do it.
Maybe this was her plan to make sure she got back in the spotlight and could begin to win Grammies and get herself back to where she was.
Maybe ari did something to her to make her upset, remember that one time when Nicki, ari and Jessie all performed Bang Bang but Jessie left ari to do the high note.
Maybe jessie was forced to play it of so she didn't look bad or was she filled with anger so much she would slit her neck open and leave her to bleed out.
