OMG! Two friends go their separate ways in a series of ROLLERCOASTER auditions! | The X Factor UK Jerrie Dilla and Tamera Foster first audition together as newly formed duo 'Silver Rock', although the Judges think they could work better as solo artists. So, through to the next stage, the girls have ONE chance to prove they can make it on thier own. But Wembley Arena is not for the faint hearted! Performances full of nerves, big vocals and even forgotten lyrics... did the judges make the right choice?
