It's the final night of auditions, and the judges must determine who will be moving on; a Howie lookalike takes the stage and a fluorescent singing act wows the judges with his original song.

Simon Cowell and Mel B bring back their chosen acts to perform one final time as the first ever Judges' Callbacks decide who advances to the Live Shows; Simon welcomes Normani and Poo Bear, while Mel reunites with bandmate Emma Bunton.
