The singer said that insurers are worried she will injure her neck after her hair got caught in the turning mechanism.
She told The Sun: "I keep being told the insurers are worried I will injure my neck. I seriously doubt it could be lethal but they want a new bra designed that will not allow hair to be caught up.
"Well, I was always known at school as the over-the-shoulder-boulder-holder."
Perry explained: "My hair got caught in the wheels of my spinning peppermint bra and began to coil around and around.
"I'm forced to just go with it so, by the end of the song, it looked quite like I was licking my own t*t. What a girl does for her art."
It was recently reported that sales of the star's Teenage Dream album surged 451% following the release of her film Part Of Me.
