• Or Jessica Ellen Cornish to her mum, dad, and close friends.


• Before JJ became a pop star she starred in Andrew Lloyd Webber's West End production of Whistle Down The Wind, attended the Brit school and co-wrote Miley Cyrus' hummable ditty, 'Party In The USA'.


• Justin Timberlake referred to her as "the best singer in the world right now" (which was in 2010, so he might have changed his mind since).


• A lot of 'industry insiders' tipped her for big things in 2011 and the Brits panel agreed, giving her the Critics Choice award.


• Her debut single, 'Do It Like A Dude', is possibly about 'the sex'.


• Her second single, 'Price Tag', was a pretty big success, as was the album 'Who You Are', which made the top 20 in America. She turned out to be a bit more ballady and seriousface than everyone first thought, but as long as you go into this expecting some selfhelppop what you get out of it is pretty great.


• She once broke her leg and didn't she fucking go on about it, Jesus wept.


• In 2012 she got a new haircut and took a role as one of the 'coaches' (judges) on the UK version of The Voice.
