"I'm just the girl with the ability to drive a man crazy/Make him come in my mouth/Make him my new baby"

"I'm just the girl with the ability to drive a man crazy/Make him call me mama/Make him my new baby"
You can listen for yourself here, but either way it's bad. Like really, really bad. Like so bad I thought it was a fake my niece recorded in her kitchen. I think they pulled some random people off the subway and made them backup singers. And Britney's next single Gimme More (listen here) opens with the words:
"It's Britney, bitch"
