Sixteen-year-old singer Rai-Elle Williams has battled through to the next round of the X Factor by singing the gospel classic 'Break every chain'. She was forced into a sing-off to decide who would go through. Three artists had to sing in front of thousands gathered at Wembley. While the two others blasted out mainstream pop hits, Rai-Elle shocked the judges by singing the words 'There is power in the name of Jesus'. Her performance saw judge Nicole Scherzinger rise to her feet, along with many in the audience. Sharon Osbourne, who is mentoring the girls' category of the ITV show, said, ‘You are fearless for a sixteen-year-old - you're unbelievable.’
