It sounds completely ridiculous when classy Yael Naim sings “I took a sip from my devil’s cup.” But those are the lyrics to Britney’s “Toxic” and she’s just being true to the original.

By producing an eerie, ghoulish verion of the buzzy pop hit, she reveal’s the song’s creepiness. “Don’t you knooooow that you’rrrrrre toxic????” Listen  at Et Musique Pour Tous. Or watch her sing it on French TV:
