The singer nearly spilled out of her top while dancing to the music, reports aceshowbiz.com.
The mishap was recorded in a video that Minogue shared on photo-sharing website Instagram.
The 47-year-old singer wore a black-and-white striped bodysuit with a zipper on the front, and a sheer white long skirt. The blonde beauty was not aware that the zipper came undone.
She just swayed excitedly to the song and the zipper was getting lower.
It almost revealed her chest before she realised and quickly zipped it up. She looked surprised and covered her top with her arms.
However, she was then laughing at the camera and said “Stop”, while walking away.
The “Locomotion” singer captioned: “When you’re filming candid stuff for #AbsolutelyAnything… But ‘NO’!!”
