The Australian singer keeps a tray of the seafood delicacy on hand to give her an instant energy boost at her shows, but her healthy habit almost ended in tragedy when one got stuck in her throat during a gig in the Republic of Ireland.
It was only the quick-thinking actions of her personal on-tour chef that saved the Spinning Around hitmaker's life.
Giles Broe, who cooks for Minogue whenever she is on the road, tells The Sunday Times Magazine: "When she's performing, I stand by the stage with a tray of oysters, which she gulps down in the breaks.
"Once, in Dublin, an oversized bay oyster got stuck in her throat.
"I panicked and slapped her frantically on the back. Once it was dislodged, we both collapsed in giggles."
