James, from Rye, will take to the stage in tonight’s episode of ITV’s Britain’s Got Talent and will perform Defying Gravity from the musical Wicked.
The performance will be watched by celebrity judges Amanda Holden, Alesha Dixon, KSI, and special guest judge Stacey Solomon.
James is competing for a £250,000 prize and the chance to perform at this year’s Royal Variety Performance.
Performers from across the UK will appear on the show each week, hoping to impress the judging panel and the voting public too.
If the judges press the golden buzzer, acts will get a special ticket straight to the semi-finals.
