Watch Katy Perry, Kelly Osbourne, Ke$ha And Basically Every Famous Person Do Karaoke
McKee herself is the songwriter behind massive hits such as Katy Perry's "Part of Me," "Teenage Dream," "Last Friday Night" and "California Gurls"; Ke$ha's "C'mon" and Taio Cruz' "Dynamite." So when it was time to debut her own music, the girl naturally called in her roster of celebrity friends for favors. Like, everyone.
The music video for her latest single is almost a who's who of the music industry with cameos by Perry, Jepsen, Ke$ha, Jewel, Jason Derulo, Tommy Lee, Kiss, Macklemore and Karmin. Other notable celebrities who pop up include Jane Lynch, Kathy Griffin, Joan Rivers, Kelly Osbourne, Giuliana Rancic, Jenny McCarthy and George Takei all taking turns singing along to the track.
"American Girl" itself is pretty much destined to be a summer jam -- and basically describes 80 percent of tweens on Tumblr -- as McKee sings of falling in love at the "7-11 parking lot" and being "raise by television." Full lyrics are now available on Directlyrics.
Take a listen to the song, above.
