ITV have announced the stars lined up to perform on the new series as the search for Britain's next biggest star continues.
The acts will be joined by the cast of Motown the Musical and last year's Britain's Got Talent winners Jules and Matisse.
The schedule is as follows:
Sunday: The cast of Motown: The Musical
Tuesday: Nick Jonas
Wednesday: Jules and Matisse
Thursday: Fifth Harmony
Stripped across the week, the live semi-finals will start on Sunday 22 May, and each night, hosts Ant and Dec will welcome nine acts to the stage to perform.
This will be their chance to win a life changing £250,000 and a spot at this year's Royal Variety Performance.
