The third set of semi finalists attempt to impress the judges and viewers at home. Luminites are tonight's stand out act and receive a standing ovation from all the judges. Others to impress include Nu Skool, Rosie and Joseph. After all the acts have performed the phone lines are opened for the third public vote of the series.
Britain's Got Talent is a reality talent show hosted by Ant and Dec. Any sort of entertainment act is able to enter the competition and hopefully impress the judges and make it through to the final stages of the competition.
The series winner's prize is £100,000 and the chance to perform at the Royal Variety Show. The judges on the show are Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams.
