The Minogues hit the stage for the first time in 30 years

Dannii is very pleased with “100 Degrees” – which features on the festive album “Kylie Christmas” – describing it as the ideal Christmas party song.

They wore matching sequinned dresses teamed with voluminous hair, and Kylie recently admitted they would be ditching the retro looks for The X Factor performance.

The glitzy production included dancers with Christmas-themed headpieces and confetti cannons which fired gold glitter on stage.

The pop pair were watched by their parents, who were in the audience.

“I love Kylie and Dannii separately but together OMG”.

Kylie will also perform, presumably alone, at the ARIA awards to be held on Thursday night – where she is due to help Tina Arena be a ushered in to the ARIA Hall of Fame.

‘I maintain someone has to get everything ready, mood the place and chop and assist and I’m great at cleaning up, ‘ Kylie said.

This year, Dannii mentored the girls.

They’re seen right here acting on The X Factor Australia’I feel we both perceive in that that’s a simple thing to put in writing about, ‘ Kylie stated.’It isn’t the truth, in that is not one thing in that you simply know, we are not scheming against one another or planning one another’s demise. However, all her acts were eliminated before the grand final.

Dannii revealed the pair have turned down numerous offers to appear together.

It was the first time the sister have sung a duet on television in 30 years – they last performed on young Talent Time in 1986 singing “Sisters Are Doing It For Themselves“.

The song 100 Degrees seems to be written with Australians in mind as it’s about a hot Christmas.
