Who's on Britain's Got Talent 2016 tonight? See the contestants on this evening's fourth Semi final line up, airing Wednesday night on ITV from 7:30PM.
12-year-old Beau Dermott wowed the judges in the first auditions of this year's series and had Amanda Holden pressing the golden buzzer.
Having brought her parents and brother Ben along to her audition, Beau admitted to being "really nervous" before her try out.
"When I'm on stage it feels like anything is possible and I can be myself," she told cameras at the time. "I really hope that I give a good performance."
Beau went on to belt out Wicked's Defying Gravity to stun the judges and live audience.
"Oh my God, you were so, so, so amazing. I am so excited for you, you were brilliant," raved Amanda after hitting the golden buzzer.
"We were not expecting that," declared Simon Cowell. "That's how you do it."
"Everyone else might as well go home, you're incredible," concluded David Walliams.
Can Beau replicate her success in the live shows tonight?
