"She's kissing my neck!" Perry exclaimed to the crowd.
When asked, the fan is barely able to make out her own name before going back to hugging the singer and resting her face on her chest.
"We might need that water back. We need some water," Perry joked before adding later, "I think she's rolling!"
The fan went on unaffected and continued to grope Perry, even going as far as grabbing one of her boobs! However, the singer didn't seem too worried about it, keeping the spaced-out girl on stage long enough to learn some words in Portuguese—like "hello" and "pizza"—and take a selfie.
After Perry finally had enough and sends the fan off stage, she tells the crowd, "Not my first and won't be my last," referencing the strange interaction.
