It was 30 years ago when fans first saw pop stars Kylie and Dannii Minogue perform together on stage.
Last night the duo treated The X Factor audience to a special song from Kylie's upcoming Christmas album, 100 Degrees.
In 1986, Kylie and Dannii sang Sister's Are Doing it for Themselves on Young Talent Time and their reunion last night was just as popular.
Do you think the girls should bring out an album together?
