Here's a recap of the Britain's Got Talent golden buzzer acts of 2015 from the auditions.
Each of the four judges - plus hosts Ant and Dec - have been able to hit the golden buzzer once throughout the try outs.
If an act gets a golden buzzer it means they're straight through to the live shows, even if all the other judges have said no as we saw last night with David Walliams' choice!
The comedian became the last to hit the golden buzzer, pressing the button for Brighton singer Lorraine Bowen who performed an original song about crumble called The Crumble Song
Simon Cowell had been the first to hit the golden buzzer this year, choosing to hit the button for singer Calum Scott who performed a unique cover of Robyn's Dancing On My Own.
Ant and Dec hit the golden buzzer in Edinburgh for dance troupe Boyband. The group's name annoyed Simon Cowell but at least he was won over by the mad performance from the former Got To Dance finalists.
Amanda Holden backed gospel choir Revelation Avenue Singers after their performance of Katy Perry's Roar.
20 strong Essex dance group Entity Allstars won the fourth golden buzzer from Alesha Dixon as they smashed their audition.
