After the tears, tension and a lot of hopping between chairs, the singing hopefuls can breathe a temporary sigh of relief that they've made it through to the judges' houses.
Nicole will be taking her "Girls" to Antigua, Louis will be flying out with the "Boys" to San Tropez, Gary will be hosting the "Groups" in New York and Sharon will welcome the "Over 25s" to her home in Los Angeles.
On hand to help each judge decide who has the potential to have a number one hit are a host of famous faces. Olly Murs will be joining Gary, Robbie Williams will be advising Sharon, Mary J Blige will be helping Nicole, and Sinitta, Nicole Appleton and Shane Filan will be joining forces with Louis.
Only three acts from each category will make it through to the live shows.
