Trivia: Katy Perry

  • Fan Nickname: She's dubbed "Fruit Sister" by her fans in China because of her fruit-themed visuals, a nickname she's happily embraced.
  • Life Imitates Art: Katy may or may not have written "The One That Got Away" before her relationship with (and subsequent marriage to) Russell Brand, but it became eerily appropriate that he filed for their divorce during the song's run as a single. He became the one that got away.
  • Missing Episode: Footage of her from the Key 103 studios has become the victim of Keep Circulating the Tapes.
  • Name's the Same:
    • Her birth name is Katy Hudson, which she used on her first album. She changed it to Perry, her mother's maiden name, in order to avoid confusion with actress Kate Hudson.
    • In 2009 her lawyers opposed a trademark filed by Australian designer Katie Perry, which is the designer's real legal name. The claim was withdrawn.
  • No Export for You: A weird case involving "Prism." The album is packaged with seeds that fans are encouraged to plant. This created a problem in Australia, which is very protective of their unique ecosystems, as the seeds could easily become an invasive species. Australia has their own version of the album containing seeds for local flora, but international versions of the album (such as those purchased online), have been quarantines as a biohazard.
  • One of Us: Katy tweeted a GIF from the CLANNAD anime series.
  • Similarly Named Works: Jill Sobule expressed some irritation over "I Kissed a Girl".
  • What Could Have Been: Sia wrote "Pretty Hurts" for Katy and did send a demo to her via email, but Katy never bothered to check her email. Sia then pitched it to Rihanna's management, but they failed to do anything with it, but Beyoncé heard the song and jumped on it.
