Ke$ha dropped by "The X Factor (US)" for a live performance on Thursday night, December 6, just a few days after she released her new album "Warrior". Wearing a black bejeweled suit, she rocked the show with fun-filled song "C'mon" and was joined by some half-naked men wearing tiger masks as dancers.
After her performance, Fifth Harmony and Diamond White battled it out for the last spot in the semifinals. The former delivered Mariah Carey's "Anytime You Need a Friend", and the latter played her rendition of LeeAnn Womack's "I Hope You Dance".
The judges were impressed by Harmony's performance more than Diamond, leading the 13-year-old girl to be sent packing. She became the second eliminated contestant that night, joining outcast CeCe Frey who was booted for getting the lowest number of votes from viewers.
