Jessie J, Ariana Grande and Nicki Minaj came together at the 2014 American Music Awards to give a live performance of their collaborative single, 'Bang Bang'. Released on 29th July, 2014, the single appears on Jessie J's 10th October 2014 album, 'Sweet Talker'.

An album re-release, a new song and a documentary mark the singer's legacy this year.
The actor plays the titular hero in the forthcoming adaptation.
