#KATSEYEonFallon #FallonTonight"It features a fun, playful introduction styled after the iconic Mean Girls movie vibe. Jimmy Fallon narrates it in classic Plastics fashion (referencing lines like describing Regina George, Gretchen Wieners, Karen Smith, etc.), but swaps in the KATSEYE members' names while they strut down a hallway in coordinated chic/black outfits looking super confident and stylish.The short video clip (about 17–18 seconds) shows the six members — Sophia Laforteza, Manon Bannerman, Daniela Avanzini (or similar lineup), Megan Skiendiel, Lara Raj, and Yoonchae Jeung — walking like a boss-level girl group, perfectly timed with the Mean Girls parody narration.The post went live on February 5, 2026 (very early morning UTC / late night Feb 4 US time), and it quickly gained strong engagement:
  • Over 16K likes
  • Thousands of views
  • Lots of excited fan replies like "YASSS GAWD", "These generational face cards", "They look so good", and praise for Sophia's acting in the bit.
This was part of KATSEYE's big late-night TV debut on The Tonight Show (aired Feb 4/5, 2026), following their recent Grammy Awards buzz. They chatted with Jimmy about starstruck moments (e.g., Manon freezing when Miley Cyrus walked by), teased upcoming new music, and overall brought high energy and stunning visuals.Fans are loving the Mean Girls theme tie-in, especially since it matches their confident, " Plastics but make it global girl group" energy.If you'd like, I can describe more about their interview segment, performance (if any), or pull up related clips/photos! 😄
