20 Bonnie McKee-Written Pop Gems To Prepare You For Her Tour

Up until recently, Bonnie McKee has been a behind-the-scenes kind of girl. Over the last decade or so, she's written some of the biggest pop hits ever and is essentially responsible for making Katy Perry the megastar she is. Bonnie has recently struck out on her own, and the world is a MUCH better place because of it. Bonnie will be joining the best boyfriend/girlfriend pop duo on the planet (otherwise known as Karmin) on tour starting next week, so here are 20 of the best songs she's ever written to get you going for the show! Want to see her live? Check out tour dates here.

Bonnie McKee - "American Girl"

I couldn't write this list and NOT include at least one song of her own, right?
