Ella Henderson and Jahmene Douglas once again triumphed over their fellow X Factor finalists as the show celebrated number one hits on Saturday night. The pair - who are among the favourites to win the series - wowed the judges with a pair of stunning performances as the remaining eight acts took to the stage. Ella made her mark with a slowed-down version of Katy Perry's Firework set to a piano accompaniment, while Jahmene reduced his mentor Nicole Scherzinger to tears with his emotional rendition of Beyonce's Listen. The singer called him a "little slice of heaven," and added, "That song was meant for you. I am so proud of you, you are lighting the torch for all the other people." Tulisa, meanwhile, told the 21-year-old his performance had left her "speechless, saying, "I guess I'll see you at the finals right?" Meanwhile, Ella's performance was described as "vocally brilliant" by Louis Walsh while Nicole added, "For a moment I forgot I was on X Factor. I thought I was in a movie." Also faring well was James Arthur, who gave his own spin to the No Doubt chart-topper Don't Speak by inserting a rap in the middle. Gary praised him for "another brilliant performance," and added, "You just seem to pull it out of the bag every week." And there was also praise for Kye Sones - who tackled the New Radicals' hit You Get What You Give - and Christopher Maloney, who rounded off the show with a soaring rendition of Eric Carmen's All By Myself. Nicole gave Kye the thumbs up for having "so much charisma" in his performance while Tulisa added, "I think the song was safe but you rocked it." The N-Dubz singer also gave a tearful Christopher Maloney a good review but added, "My only issue is it's five weeks too late. It shouldn't take someone so long to get to this stage." Louis however wasn't so keen, saying, "Watching you, I feel like I'm in a time machine," - although his attempts to start an argument with Gary Barlow over the Liverpudlian were quashed by Dermot O'Leary bringing the show to a close. Meanwhile there were mixed fortunes for the two remaining groups, with Union J winning good reviews for their rendition of Taylor Swift's Love Story - but District 3 being roundly criticised for their upbeat rendition of Taio Cruz's Dynamite. "I don’t know who you are anymore. I’m lost, I don’t get it," Gary told the boyband while Nicole criticised Louis' choice of song. "If we were at the Mickey Mouse cub this would be amazing, but this is the X Factor where they eat you alive," she said. "You can’t have them come out and do that and then have Union J do what they do." It was also a mixed night for Rylan Clark, who kicked off the show with a medley of Madonna's Hung Up and Abba's Gimme Gimme Gimme - which Louis called "over the top but brilliant and enjoyable". However Gary once again wasn't so sure. "The vocals at the top weren't too bad actually," he admitted, "but after that it was chaos, drama - I enjoyed everything but you actually." The results will be revealed on Sunday evening, with one more act eliminated from the competition.
