The judge will take to the stage for a performance during Thursday night's live results show to premiere the track, which was written by Babyface.
Speaking to the X Factor official website, the singer said: "I'm not particularly nervous [performing in front of] Simon because I know I have his support. What people don't see is that we really are a family.
"I am nervous, however, to perform the song because I've never performed it before. We just finished recording it and we're still working on the production of it."
She added: "I can't wait for my fans to hear it. The lyrics are unbelievable and hopefully people can relate to it... This is really coming from my heart and soul, so hope you feel it."
Scherzinger's last remaining contestant Josh Krajcik is one of the four contestants still in the running for the $5 million prize. They will take to the stage tonight (December 14) for their semi-final performances.
Thursday night's results show will see this season's final three named and also feature a performance from Florence + the Machine.
Other guest performers this season have included Rihanna, Bruno Mars, Kelly Clarkson, Lenny Kravitz, Jessie J and Mary J Blige.
X Factor airs tonight (Wednesday, December 14) at 8/7c on Fox.
