time, Perry expressed interest in having "a co-writer I could volley with", adding that "Bonnie and I are on the same zeitgeist tip." Perry and McKee (along with Max Martin and Benny Blanco) began writing songs, eventually producing the hits that would appear on Perry's third album, Teenage Dream. McKee co-wrote three singles from the album, "California Gurls", "Teenage Dream", and "Last Friday Night (T.G.I.F.)", the last of which was inspired by McKee and Perry's misadventures in their teenage years. Each of the singles topped the Billboard Hot 100 chart, and they earned McKee several BMI Pop Awards in 2011 and 2012 for her role as a songwriter. McKee also co-wrote two more chart-toppers for Perry, "Part of Me" and "Roar" as well as four other songs which hit number one on either the Hot 100 or the UK Singles Chart, Britney Spears' "Hold It Against Me", Taio Cruz's "Dynamite", Rita Ora's "How We Do (Party)", and Cheryl's "I Don't Care". On June 22, 2017, the Recording Industry Association of America (RIAA) announced that "Roar" had received an RIAA Diamond certification award for 10 million copies sold. In 2012, McKee co-wrote two songs that appeared on Adam Lambert's album Trespassing, which debuted at number one on the Billboard 200 Album Chart. She appeared as a featured performer on "Thunder" from Rusko's album Songs, released on Mad Decent. During this time she signed a recording contract with Epic Records. She had garnered attention for her fashion sense, appearing on E!'s Fashion Police, and appearing on the pages of The New York Times, New York Post, and Schön! Magazine. In 2013, McKee was awarded with three more BMI Pop awards for her songwriting work on Katy Perry's "Wide Awake" and "Part of Me", as well as Britney Spears' "Hold It Against Me". McKee's first single under Epic Records was "American Girl", which was released on July 23, 2013. She posted a promotional video for "American Girl" on YouTube in June 2013 which garnered 2.3 million views. The official music video for the song was released on July 22, 2013. In October, McKee released a new song titled "Sleepwalker". McKee confirmed that the song was not a single, but rather an "inbetweengle", a portmanteau meaning "in between single", meant to tide fans over until her next official release. The music video premiered on October 17, 2013, and starred McKee and Kelsey Chow. McKee
