The only girl group to get through to any final of the X Factor was mentored by none other than Tulisa Contostavlos. 2011 is the first year that Tulisa was a judge on the X-factor, in it's eighth series of the highly popular show. It was a case of the young ones on this year's X Factor with acts mentored by the new judges all getting through to the final. Amelia Lilly is mentored by Kelly Rowland and Marcus Collins by Gary Barlow.
