The former Disney star walked around the stage on March 20 concert while talking to the crowd before drinking from a bottle and spitting water all over them, reported Ace Showbiz.
The 21-year-old singer, who took to the stage in a sparkly red leotard, did it three times.
However, her fans did not seem to be bothered by the stunt. Instead, they enjoyed it as they're heard screaming and cheering.
Cyrus is currently on her ongoing Bangerz tour, which was launched last month to support her latest chart-topping album Bangerz.
