The 'Domino' singer joins will.i.am, Tom Jones and Danny O'Donoghue in the trailer for the new reality show.
Jessie J joins fellow The Voice UK judges will.i.am, Sir Tom Jones and The Scripts Danny O-Donoghue in the first teaser trailer for BBC1's new music reality series.
The 'Who You Are' singer will star as a vocal coach on the British version of the popular US series, which launched in 2011 with a panel including Cee Lo Green, Christina Aguilera, Adam Levin and Blake Shelton.
The Voice UK follows a premise which sees all four vocal coaches sitting through blind auditions with their backs turned on the auditionees, after which they select their acts based on the hopeful contestants' voice alone.
The Voice UK is due to begin on BBC1 later this month.
