Gellar is going to be playing Kathryn Merteuil again, 17 years since she portrayed the seductive teenage character in the 1999 cult film.

Sarah will be playing Kathryn in NBC's upcoming TV show which will act as a sequel to the original movie.

The blonde star announced the news on her Instagram account, posting a photo with the movie's original director-and-writer Roger Kumble and the film and show's executive producer Neal Moritz.

The accompanying caption read: "Throwbackthursday (a bit early in Los Angeles) this picture was taken on the eve of production on the original #cruelintentions. Its me #rogerkumble (director) and #nealmoritz (exec producer) and the other is a picture of us now on the eve of production on the new #cruelintentions. That's right "everybody loves me, and I intend to keep it that way "#kathrynmerteuil is back!!! I am happy to say that I will be joining them (and @nbctv ) on the new #Crueltv (sic)"

The 'Cruel Intentions' TV series will follow Kathryn's quest to control Bash, the son of Annette Hargrove - played by Reese Witherspoon in the film - and the deceased Sebastian Valmont, who was portrayed by Reese's ex-husband Ryan Phillippe, as he leaves his small Kansas town to learn more about his family's legacy at Brighton Preparatory Academy.

Taylor John Smith will play Bash and Samantha Logan has also been cast in the project.
