Six reasons Jessie J is a perfect judge for The Voice
1. She is good at sitting down.
2. We might find Jessie saying that breaking her foot gives her different respect for people who don't have legs (http://www.guardian.co.uk/music/2011/oct/02/jessie-j-legs-remark) ridiculous in the extreme, but that sort of thing will be great on TV.
3. She will be able to give some amazing seriousface bon mot action when booting people off.
Jessie: "It's okay not to be okay!"
Contestant: "So am I still in the show then?"
Jessie: "Well no."
