Her little sis recently quit the X Factor amid arguments about scheduling, and Kylie said that she hopes they can now find the time to team up.
Kylie, 43, told The Sun, 'We would definitely love to do something together again, or many things in the future.'
The Aussie pair once recorded a cover of Abba's The Winner Takes It All for UK TV show Beautiful People in 2008, and performed together on Kylie's Showgirl tour.
But Kylie added, 'My favourite thing that we have done together is a comedy catfight for a sketch show in England a while back.
'She and I speak the same language - we both have been in showbiz a long time.
'We know the ups and downs of it.'
