Ellie Goulding, Nicole Scherzinger and Shane Filan will duet with the final three X Factor contestants on Saturday night's finale.

Scherzinger will take to the stage with Sharon Osbourne's remaining act, Sam Bailey and they will perform And I Am Telling You from Dreamgirls. Nicholas McDonald will be joined by Westlife's Shane Filan for a rendition of Flying Without Wings and Luke Friend will sing Anything Can Happen with Ellie Goulding.

Since the judges houses stage of the competition Filan has been a fan of Nicholas, "Nicholas stood out from the beginning as he has such an incredible voice for someone so young. It's been exciting to watch him every weekend, and I hope that I can help him in the final to go all the way."

Scherzinger is delighted to perform with Bailey saying, "I'm so excited to be singing with the beautiful and talented Sam Bailey. We're going to have so much fun and scha-diva it out this weekend on the X Factor stage! Stay tuned."

Goulding also expressed her happiness about her duet, "I'm really excited to perform with lovely Luke. He's a crazy talented singer and a good soul and to me that is the perfect combination. I love the tone of his voice and his stage presence. It's very, very cool to be a part of the live X Factor show."

The rest of the songs that will be performed at the live finale will be released this weekend but it's guaranteed to be a good show with One Direction, The Killers, Katy Perry, Elton John, Gary Barlow and Tom Odell set to perform over the course of the weekend.
