Have you heard Bonnie McKee's new song, 'American Girl' on Mix 93.1? While this may be the first song you've heard from her, Bonnie is no stranger to the music business.

 

 

She is also a friend of Katy Perry's and co-wrote the hits 'California Gurls,' 'Teenage Dream,' 'Last Friday Night (T.G.I.F.),' 'Part of Me,' 'Wide Awake,' and 'Roar.'

'American Girl' is the first single off of her second album, which is  expected to release in Spring 2014.

Bonnie also collaborated with her musical buddies in this video.

Can you name all of the cameos by other artists?
