Here's a rundown of the nine acts on tonight's first Britain's Got Talent 2013 semi-final line up.
The auditions have only just finished but the live shows kick off this evening with the first semi-final heat.
Between now and Saturday there will be five live shows, with nine acts competing in each.
The judges - Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams - will of course be on hand to offer their opinions, but it'll be us viewers who will vote for our favourite.
The act with the highest number of public votes automatically goes through to the live grand final while the two runner-up acts will then face the judges who will pick their favourite to go through to the live shows.
This evening's first BGT semi-final line up is still to be fully confirmed for the first four acts have been revealed.
There's magician Darcy Oake, musical theatre group Collabro, 12-year-old dancers Lauren and Terrell and the 18-person-strong dance troupe CountryVive.
Joining them are Comedian and impressionist Jon Clegg, singer Henrietta Adewole and David Walliams’ Golden Buzzer act Christian Spridon.
Britain's Got Talent 2014 airs tonight, live on ITV from 7:30PM.
