Alesha Dixon has become the fourth and final Britain's Got Talent 2014 judge to press the golden buzzer at today's auditions in London.
A new twist for this year's series of the show, the golden buzzer gives the panel the power to send acts straight through to the live shows, without consulting the other judges.
However, each judge can only press the special button once - and this afternoon saw Alesha hand out the last guaranteed place in the finals to a lucky act, who have yet to be identified.
Amanda Holden broke the news on her Twitter page, writing: "Alesha pressed her golden buzzer!! #finally"
Holden was the first to hit the golden buzzer, on a salsa dance act in Birmingham, before Simon Cowell used it during an 'emotional' performance at the Manchester try-outs.
David Walliams then backed another mystery act during the first day of London auditions on Monday.
This means there are no fast-tracks available for the remaining hopefuls, with one more day of filming set to take place tomorrow.
Britain's Got Talent is expected to return to our screens in April.
