2011, Jepsen recorded material for her second album with Josh Ramsay, Ryan Stewart, and Tavish Crow, her co-writer of "Call Me Maybe". The track was released in September of that year. 2012, fellow Canadian pop singer Justin Bieber promoted the single on Twitter, and the next month, it was featured in a viral video in which Bieber, Selena Gomez, and Ashley Tisdale lip-synced and danced to it. Bieber's manager, Scooter Braun, signed Jepsen to a joint worldwide record deal with his label, Schoolboy Records, and the major label Interscope Records. "Call Me Maybe" later peaked at number one on the Canadian Hot 100, making Jepsen the fourth Canadian artist to top the chart. In the United States, the single spent nine weeks at number one on the Billboard Hot 100, earning the title "Song of the Summer" from Billboard magazine. The single also topped the charts in 18 countries, including the United Kingdom, where it was the year's second best-selling single. It was the best-selling single of 2012 worldwide, according to the International Federation of the Phonographic Industry (IFPI). The song was included on Jepsen's six-track EP, Curiosity, released in February 2012 in Canada.
