The nation's favourite singing show continues into its third weekend of the live shows as the remaining contestants take to the stage to perform for the judges and audience at home, all in the hope of sealing their place in the competition for another week. This year the stakes are higher, as the most popular act over the weekend will win a money-can't-buy prize. Resident host Dermot O'Leary leads the proceedings, as the four judges battle it out to keep their acts in the show. This year Louis Walsh has the Boys, Nicole Scherzinger the Overs, Simon Cowell the Groups and Sharon Osbourne the Girls. Throughout the live shows an outstanding line-up of guest stars will perform.
