WATCH: Kylie and Dannii Minogue reunite on The X Factor Australia to perform their first TV duet in 29 years
It was wonderfully camp, of course.
Has it been that long? Kylie and Dannii Minogue have reunited to perform live on television for the first time in nearly 30 years.
The Australian sisters performed their disco-infused Christmas song '100 Degrees' on The X Factor Australia, taken from Kylie's new Christmas album Kylie Christmas.
WATCH & ENJOY:
The two have appeared together at live shows over the years, and have even collaborated, such as in 2008 when they covered ABBA's 'The Winner Takes It All'.
Yet this is the first time they have performed together on television since 1986, when they covered 'Sisters Are Doing It For Themselves' for variety show Young Talent Time - mullets and all.
The duo recently unveiled the video for '100 Degrees'.
Also included on Kylie's Christmas album is a duet with James Corden called 'Only You', which started as a joke but was released for real after it impressed the producers.
It even makes that John Lewis advert a little better too.
