Jessie J released her second studio album in September 2013. Jessie co-wrote the album with Claude Kelly, amongst a host of collaborators including Becky G, Brandy Norwood, Big Sean and Dizzee Rascal. The album debuted in the Top 5 on the UK Albums Chart. It included two top-five hits including “Wild” and “It’s My Party”. Jessie supported Alive with the Alive Tour, playing 19 dates across the UK, from October to November 2013.

In July 2014, the first single from her sophomore, Sweet Talker album arrived with a bang—literally.Jessie J teamed up with rising diva Ariana Grande and rap’s reigning queen Nicki Minaj for “Bang Bang”. It’s a blockbuster anthem, combining Jessie J‘s inimitable delivery, Ariana Grande‘s massive range, and Nicki Minaj‘s deft wordplay. As soon as “Bang Bang” dropped, the charts exploded. Immediately, the track captured the #1 spot on iTunes Overall Top Songs Chart and it has gone Platinum four times over less than a year after release. The single perfectly set the stage for the October 2014 release of Sweet Talker, which debuted Top 10 on the Billboard 200 and included appearances from De La Soul, 2 Chainz and American violinist Lindsey Stirling and production from the likes of Max Martin, Savan Kotecha, Ilya, Diplo, Tricky, The Dream and more.

Jessie J released the first single entitled "Flashlight" from the highly-anticipated sequel to the smash hit and platinum-selling soundtrack, Pitch Perfect in April 2015. Her new album R.O.S.E. is due out in 2018 and has been preceded by the moving singles "Think About That" and "Not My Ex".
