Sounds like Katy with a hint of Bonnie

Sounds like Bonnie not really Katy.

I can kind of hear her, just.

Totally Katy and some other random person.

It really does sound like Katy in the chanting parts... not so much the singing chorus. It could be Bonnie but it's obviously edited a lot, so it doesn't really sound like either of them that much.

that's totally her at the speaking part
