When you think that her sexual antics have nowhere left to go, she pops up with yet another incredibly vulgar display which makes our jaws hit the floor in utter shock.
Straddling an inflatable penis on stage, dramatically poised between her legs with her tongue protruding as if to signal the onset of a sexual climax, she leaves her audience gasping for breath.
The former Disney star has almost become off-limits while performing at United Center in Chicago in front of thousands who must have felt that perhaps they were in the wrong venue, or better still watching what we might call an erotic gyration which unlocks closed doors where the forbidden fruit is about to make an unexpected appearance.
Her unpredictability as a performing star is becoming the stuff of legend.
With her short blonde hair tied into a bun on the top of her head, the chart-topper twerked with the phallic object in a multitude of ways before finally pressing it against her crotch.
She could not have been more outrageous even if she willed it. But with Miley her horizons are so infinitely huge that nothing is beyond her reach.
Her fertile imagination will somehow lead her to unchartered territories and her capacity to shock has not had its surfeit yet.
Good old Miley will I’m sure continue to give us a taste of what some of us have been missing. It is not, however, for the faint-hearted.
