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 a real mixed bag, with the likes of favourites including singers Band of Voices and impressionist Philip Green.
There's also 11-year-old performer Arisxandra Libantino, Welsh brothers Richard and Adam, and teenage duo J-Unity, as well as a more wacky vocal pairing in the form of drag act Bosom Buddies.
Meanwhile, there's dance from Youth Creation and another daring illusion from Aaron Crow.
Finishing the line up is 'dancer' Martin Healy, who somehow has made it this far with his nun act.
Britain's Got Talent 2013 airs tonight, live on ITV from 7:30PM.
