The Girls Aloud star halts South Wales student Lloyd's audition after he hits some bum notes in a rendition of Jason Mraz's 'I'm Yours'.
Simon Cowell suggests that he sing acapella and the young singer attempts to make amends with a version of R Kelly's 'If I Could Turn Back the Hands of Time'.
Before he performs, Lloyd tells the cameras: "I'm 16 years old and I'm a student from South Wales. I am nervous, singing in front of four judges and 2,000 people today. So I just hope it doesn't show in my performance."
The X Factor airs on Saturday at 7.35pm on ITV1. The Xtra Factor follows afterwards at 8.35pm on ITV2.
