Background The song was originally conceived during a studio session between Charli XCX, Ali Tamposi, Jack Patterson of Clean Bandit, and Andrew Watt, the last of whom produced the song. Watt, prior to the studio session, created a guitar melody that he described as being reminiscent of Fleetwood Mac and José Feliciano. He played the guitar melody during the studio session where ideas for melodies and lyrics were created to accompany it. The melody and lyrics for the chorus of the song eventually formed, including what would become the opening line, "I love it when you call me señorita". Watt sent the rough chorus of the song to Shawn Mendes, suggesting that the song be recorded as a duet, to which Mendes agreed and said that Camila Cabello would be "the only person" with whom he could do the song. Watt then sent the song to producers Benny Blanco and Cashmere Cat who liked it and began to work together on the production of the song, deciding to keep it simple to make room
