33-year-old full time mum Linzi Martin had her first pop at fame in a group called Girl Thing, who were signed to RCA Records by none other than Simon Cowell. But how will Simon react when his former protegé walks into the room auditions?
Awwww we LOVE pugs too! In fact we might pop out and get ourselves a pug jumper like Andrea Faustini, but this Roman was definitely not what the Judges were expecting! He loves The X Factor UK so much, he came all the way from Italy (with his little Scary Spice doll) to audition.
Jimmy Cheung is 57 and from Hong Kong, but decided to add a dash of Italy to the auditions with his rendition of Luciano Pavarotti's O Sole Mio (translated means My Sunshine don't you know!) but was the sun shining for Jimmy after his audition when Simon told him he would be remembered?
19-year-old French au pair Oceane Guyot, travelled all the way from Paris to appear at the room auditions after watching The X Factor UK and seeing an Englishman win The X Factor in France. So she thought she'd try her luck with Mariah Carey's Emotions. See the Judge's emotions after the audition
When Kitten and the Hip turned up at the auditions, the Judges weren't quite sure how this duet would work, and after seeing them perform Shut Up and Dance, they all made their feelings very clear. But how would Kitten react to the news?

Concept are five lovely lads from Hampshire, and have been together for the last three and a half years. They surprised the Judges with an exciting new version of Labrinth's hit single Earthquake. But will Karim, Scott, Matt, Nathan and Ben do enough to move Simon Cowell's world?
