Warning spoilers!

After Tuesday night's slightly underwhelming semi-final, Britain's Got Talent viewers were spoiled during last night's show, with a line-up that included two Golden Buzzer acts.

But just as the show kicked off, viewers noticed that Birmingham-based dance act AcroCadabra had gained an extra member... in the form of crew member that didn't make it off the stage in time. 🙈

As the youngsters gave an upbeat performance, a stunned looking crew member appeared on stage, with his head clearly in view behind a glass box.

Viewers were quick to spot the mistake, taking to Twitter to express their humour...

Unfortunately for AcroCadabra, gaining an unwanted extra member wasn't enough to help them land a spot in Sunday night's final.

Funnyman Robert White topped the public vote after his hilarious routine, which included a song about the four judges.

Check out his performance below:

With the judges unable to decide between Amanda's Golden Buzzer act Gruffydd Wyn, and singer Aleksandar Mileusnić, the decision once again was left with the public.

Show host Declan Donnelly then announced that Welsh singer Gruffydd Wyn would join Lost Voice Guy, D-Day Darlings, Donchez Dacres, Calum Courtney and Robert White in Sunday night's live final.

Now check out all of the previous Britain's Got Talent winners:
