Skirt is the first taste of Minogue’s work since signing with Jay Z’s management company Roc Nation.
The song sees Minogue sing the line “and then my skirt came down” over dubstep and electro beats, complete with sighs and moans.
It is unclear whether the version online is a remix or the final version of a new single.
The song was made with Scottish dance producer Nom De Strip, aka Chris Elliott, and is co-written with Beyonce and Rihanna hit maker The Dream.
Elliott posted the song on Twitter after it was aired in Ibiza.
The chorus runs “Tonight, be my supernova, take whatever you want, Tonight, let me bask in you like rays of the sun/tonight I’m yours.”
Minogue has been in the studio with fellow Australian Sia, as well as Rodney Jerkins, Pharrell Williams and Lady Gaga producers Red One and Fernando Garibay for what will be her twelfth album. It is due for release later this year.
