Jessie J, affectionately referred to as Messy J by non-fans, is back with her fourth UK single, "Who's Laughing Now". Messy was recently announced as a special guest act for a handful of Katy Perry tour dates stateside later this year, and will also be headlining her own UK tour this autumn, kicking off in Birmingham on October 17th.
The track features Jessica triumphantly calling out her "haterz". The accompanying visual, available below, portrays her in a number of guises - child, grown, teacher, dinner lady. Enjoy:
