& Juliet is a 2019 jukebox musical featuring the music of Swedish pop songwriter Max Martin, with a book by David West Read, in which Anne Hathaway negotiates with her husband, William Shakespeare, to change the ending to Romeo and Juliet so that Juliet does not kill herself. Juliet's parents plan to send her to a convent, so she flees to Paris, accompanied by her nurse, a friend and Anne herself, who writes herself into the play as a new character, "April". Shakespeare resists Anne's ideas, and the story unfolds as a tug-of-war between the two writers, with Juliet consequently buffeted between lovers and advisers, as Anne seeks a happy ending for her.

& Juliet premiered at the Manchester Opera House in September 2019, before transferring to the West End in November 2019. At the 2020 Laurence Olivier Awards, & Juliet received nine nominations and won three awards, including Best Actress in a Musical for Miriam-Teak Lee in the title role. The West End production also received a record-breaking 13 nominations at the 2020 WhatsOnStage Awards, ultimately winning six awards. The 2022 Broadway production was nominated for nine Tony Awards, but did not win any.

One of the Boys is the second studio album by American singer Katy Perry. It was released on June 17, 2008, by Capitol Records. She collaborated on the album with producers Greg Wells, Dr. Luke, Dave Stewart, Max Martin, and Ted Bruner among others, and wrote most of the songs in collaboration with other producers and writers. Perry wrote its title track along with "Thinking of You" and "Mannequin" alone, with "Thinking of You" being written back in 2002. The extended play (EP) Ur So Gay (2007), containing her song of the same name (later released as a promotional single), was released before One of the Boys to generate interest in the singer and the then-upcoming album.

Commercially, it charted within the top ten in Argentina, Austria, Canada, Denmark, France, Germany, Ireland, Mexico, Norway, Switzerland, and the United States. One of the Boys earned Perry two Grammy Award nominations, and has sold seven million copies worldwide. It has been certified Diamond in Brazil as well as multi-platinum in Australia, Canada, Chile, Denmark, Finland, France, New Zealand, Norway, the United Kingdom, and the United States.
