Since its release in 2004, the ever-quotable Mean Girls has cemented its place as a comedy classic.
It helped launch its cast, which includes Lindsay Lohan, Rachel McAdams and Amanda Seyfried, into Hollywood stardom, quickly becoming a pop culture phenomenon, from Pink Wednesdays to commemorating October 3rd.
The film was even turned into a hugely successful Broadway musical in 2018, earning multiple Tony Award nominations and its very own film adaptation which is set to hit cinemas in early 2024.
It will star Reneé Rapp, who will reprise her Broadway role as Regina George, alongside the likes of Angourie Rice, Jon Hamm and Busy Philipps, with others such as Ashley Park, who originated the role of Gretchen Weiners in the musical, and Tina Fey, who wrote the original screenplay, also set to appear.
But if you're wondering how the 2024 Mean Girls cast compares with to the original, don't worry - here they are side by side.
