'X Factor': Florence + the Machine, Nicole Scherzinger set as musical guests

florence-machine-getty.jpgIf fans of "The X Factor" aren't satisfied by the final four contestants, they'll have a couple great musical guests to keep them entertained. And one of those performers won't have to travel very far to hit the stage.

The singing competition announced that Florence + the Machine and "X Factor" judge Nicole Scherzinger will perform during the results show on Dec. 15. This comes just a week after hit makers Lenny Kravitz and Mary J. Blige sang.

Scherzinger, herself a former reality show winner, was the lead singer for Eden's Crush and later The Pussycat Dolls. She will be singing a tune from her forthcoming solo project.

Florence + the Machine are the Grammy-winning indie rock band. The London-based group is currently promoting their second album "Ceremonials."

"The X Factor" results show airs on Thursday (Dec. 15) at 8 p.m. ET.
