Gary Barlow, Nicole Scherzinger, Tulisa and Louis Walsh have chosen the 24 contestants who will go to Judges Houses, and now they are each faced with the task of choosing their final three acts to take through to the live shows. Gary is at an English stately home, Nicole is at a luxury resort in Dubai, Tulisa is on the Caribbean island of St Lucia, while Louis is in Las Vegas. The mentors are helped to make their decisions by Cheryl Cole, Ne-Yo, Tinie Tempah and Sharon Osbourne respectively. The contestants must sing with a just a piano or guitar in a bid to secure their place in the live shows - and not only do they need to impress their mentor, they have to blow their special guest away too.
