Singer Kylie Minogue is set to stun her fans by releasing an X-rated new promo in which she writhes with four women during a 'sex workout'.

The Australian pop star unveiled a video for her new single Sexercize on Tuesday (18Mar14), but on Wednesday (19Mar14) she revealed a raunchy alternative film.

It shows the Spinning Around hitmaker wearing a white leotard and red high-heeled shoes as she performs a series of suggestive exercise routines with an inflatable gym ball and on a pommel horse.

She is then shown wearing a flesh-coloured leotard while licking beads of sweat off a similarly-dressed model before receiving a saucy massage from four other women as the promo ends.

Minogue is also celebrating the release of the track by launching a website on Wednesday, featuring several more interpretations of the raunchy song, including "Kylie's own personal content".
