Breakout star Bonnie McKee, who has co-written No. 1 hits for Katy Perry, Britney Spears, and Taio Cruz, has watched her solo career heat up to a full boil ever since she unleashed a viral video for her debut single “American Girl” — an anthemic pop tune that showcases her powerhouse voice, knack for big choruses, and nostalgia-tinged lyrical point of view. The viral video (which can be seen here) is packed with celebrity cameos by Perry, Tommy Lee, KISS, Ke$ha, Adam Lambert, Carly Rae Jepsen, Joan Rivers and many others lip-synching along to the song. The star-studded clip, which has seen over one million views, has led to a wave of press attention, with several outlets calling “American Girl,” which is climbing the Top 40 radio chart, the “Song of the Summer.” McKee will perform the song on Good Morning America on August 15th. In addition, McKee has debuted the official video for “American Girl” on VEVO this week already pulling in over a million views.
