Not only did Demi Lovato serve as a judge, but she also made an appearance as a performer on Thursday, November 28 episode of "The X Factor (US)". That night, the 21-year-old singer treated audience and fellow judges with a live rendition of her "Neon Lights".
Dressing up as a sexy lady rocker, Lovato belted out the newest single off her self-titled album, "Demi". She was joined by several back-up dancers on the stage that'd been decorated with neon lighting. During the performance, the light dimmed and Lovato showed off her glow-in-the-dark lips and nails.
Before performing, Lovato tweeted her excitement, writing, "More #xfactor tonight!! I'm performing #neonlights!!!!! #happythanksgiving."
It was a tough Thanksgiving Day for two "X Factor" contestants, Rion Paige and Josh Levi, who were eliminated from the competition.
After finishing this season of "X Factor", Lovato will embark on her "Neon Lights" tour next year. She's set to bring along Fifth Harmony and former contestants of U.K.'s "The X Factor", Cher Lloyd and Little Mix.
