Saara Aalto is the new one to beat after her latest performance on The X Factor 2016 tonight.
Last week the jukebox picked out a Christmas theme for this week's semi-finals.
And Saara gave it EVERYTHING with an epic mash up of White Christmas and Mariah Carey's All I Want For Christmas is You in her first performance of the night.
For her second song, Saara chose to reprise her audition performance of Sia's Chandelier as the final four each chose tracks to get them to the final.
Louis Walsh gushed: "It's very simple you deserve to be in the final, you're a world class act. That as amazing performance, I love everything about you.
Nicole Scherzinger told Saara: "This is the song that you sung that blew me away and it was the reason why I chose you as the wild card."
She joked: "I'm starting to regret that I chose you as you're so unbelievable! I love a fighter."
Simon Cowell reacted: "Oh bleep. Apart from the silly dress it was absolutely sensational. I thought the arrangement was stunning."
Finally, Saara's mentor Sharon Osbourne was left speechless and close to tears.
"That was a moment for me, my hand was shaking through the whole song, I was so emotional, I loved every second of it," Saara told Dermot O'Leary after the performance.
