Dannii and Kylie Minogue are set to perform at this year's X Factor grand final on November 24.
The Minogue sisters will perform 100 Degrees, the first single off Kylie Christmas, in their first television performance in almost three decades.
Minogue (Kylie) said she would be bringing a little Christmas cheer to The X Factor stage.
"I can’t wait to come home and perform on the show with Dannii,” she said.
The Minogues last teamed up on the 2013 season of X Factor when Kylie was Dannii’s special guest at Home Visits in New York.
