Kylie Minogues

Kylie and Dannii Minogue to perform on TV for the first time in nearly 30 years on X Factor

The sisters’ last duet in a TV studio was on Young Talent Time in 1986.

Their iconic performance of Sisters Are Doin’ It For Themselves saw the then teenagers covered in sequins and with gravity-defying ‘80s hair.

“We’re not going to be able to give nearly as good hair this time around,” Kylie said. “Or outfits, or anything like that. We literally can’t beat that. So we can only aim to honour it.”

The Minogues will perform 100 Degrees, a disco-influenced duet from Kylie’s newChristmas album.
