Britain's Got Talent returns for a fourth round of live semi-finals this evening as eight more hopefuls take to the stage at London's Hammersmith Apollo.
Judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams will be watching as the contestants attempt to impress them and bag a place in this Sunday's final.
However, only two acts will be allowed to go through and win the chance to perform at the Royal Variety Show.
