Mean Girls writer Rosalind Wiseman claims she hasn’t seen a penny from her co-writer Tina Fey or Paramount since their hit film grew into one of the studio’s biggest comedy brands.

While Wiseman should be out promoting the new musical based on her hit book Queen Bees and Wannabes, instead, the writer is opening up about the “painful experience” which led to her losing the royalties to her original story.

The 54-year-old writer was paid $400,000 after signing her deal with Paramount, but has yet to see a single dime related to the hit Broadway musical, video game adaptation or the 2011 made-for-tv sequel on Freeform.
