WATCH: Bonnie McKee's 'American Girl' Video

We told you about Bonnie McKee when her homemade video for her first single, "American Girl," that included her celeb pals--Adam Lambert, George Takei, Lance Bass, Kathy Griffin, Katy Perry, Joan Rivers--showed up. And although most people may not recognized her quite yet, McKee has co-written songs for an array of A-list pop stars, including Katy Perry, Britney Spears, Ke$ha, Carly Rae Jepsen, Christina Aguilera, Kelly Clarkson, and Taio Cruz, racking up eight No. 1 singles, including Perry's "Teenage Dream" and "California Gurls," Spears' "Hold It Against Me," and Cruz's "Dynamite". Now the "official" video is available with shirtless boys, booty shorts, and more summer silliness--think The Bling Ring meets Spring Breakers--so check it out below:
