Susan Boyle might already be stealing the show on Britain’s Got Talent, but a twinkle-toed 10-year-old looks set to give her some stiff competition.

Hollie Steel, from Accrington, Lancashire, wows the judges in the next edition of the ITV1 show with an all-singing, all-dancing performance of I Could Have Danced All Night from the musical My Fair Lady.

At auditions in Manchester – where last year’s dancing winner George Sampson was discovered – Hollie took to the floor in a lilac tutu and began her ballet routine.

Not a man to suffer little girls in lilac tutus gladly, judge Simon Cowell reached for his buzzer to dismiss her when she started singing, prompting the audience to rise to their feet and judge Amanda Holden to sing along.

After the performance, judge Piers Morgan tells Hollie: “We have seen a lot of children on our show over the last three series and I have never heard any of them sing as well as you do.”

Earlier this week, Piers wrote on his blog that the show had a “tiny young girl singer … who will melt your heart”.

This Saturday’s show also features Kelly Brook’s short-lived appearance as a judge.

In January the model and presenter was axed just a week into filming when producers decided the four-judge format was over-complicated.

Britain’s Got Talent is on Saturday at 8pm on ITV1.
