Mean Girls game trailer
From The Lost Media Wiki
I'm surprised that this wasn't put on here yet, but the same site with the screenshots also has a trailer. The game's full title was "Mean Girls: High School Showdown", and the translated text described the game as "the teenager game based on the movie of the same name with Lindsay Lohan." The link for the trailer is here- https://multiplayer.it/ricerca/?q=Mean+Girls+per+Nintendo+DS (Archive, just in case: http://archive.is/JfqQ6 )
