In 2004 she released her debut album, Trouble, with Reprise Records, but soon switched her focus to working as a behind-the-scenes songwriter. She has written ten songs that have hit #1 in either the US or UK, and is best known for her work with Katy Perry, which began with the Diamond-certified and international chart-topping album, Teenage Daydream. Bonnie contributed to three songs on the album, all of which became chart-topping singles: “California Gurls,” “Teenage Dream,” and “Last Friday Night (T.G.I.F.).” When the deluxe Complete Confection version of the album was released, Bonnie landed two more chart-topping singles with “Part of Me” and “Wide Awake.” She went on to collaborate with Katy Perry on four songs on the follow-up album, Prism, including the Top 20 single “Birthday” and the #1 hit “Roar.” Other successful singles from the Bonnie McKee songbook include “Dynamite” for Taio Cruz, “Hold it Against Me” for Britney Spears, “C’Mon” for Kesha, and the UK chart toppers “How We Do (Party)” by Rita Ora and “I Don’t Care” by Cheryl. Additionally, she’s written songs for Cher, Christina Aguilera, Kelly Clarkson, Avril Lavigne, Bebe Rexha, Jason Derulo, Kygo, and Adam Lambert, among others.In 2013, Bonnie reemerged as an artist with the single “American Girl” on Epic Records. She recorded an entire album, but parted ways with the label and it was shelved. Enough tracks and demos leaked online over the years, however, that fans were clamoring for it. Now, more than ten years later, Bonnie has re-recorded the album. She combined the re-recorded tracks with the original release of “American Girl,” which has now been streamed 23 million times on Spotify. The end result is Hot City, an album more than a decade in the making.
