Bella Thorne will guest star on CBS' long-running mystery drama, 'CSI,' this Sunday, Oct. 19 and in this clip shared by J-14 (via Yahoo!), we see her act as a high school "mean girl" type.

The episode, titled 'The Book of Shadows,' has the CSI team investigating a mystery at a high school when a chemistry teacher is set on fire. Is it an accident or foul play?

Thorne will reportedly be playing a character named Hannah who is a bit of a bully to her next door neighbor, but also has a dark and secret past.

It's been a busy year for Thorne in front of the camera, who has come a long way from Disney's 'Shake It Off.' In addition to 'CSI,' Thorne was also seen in the recent family comedy, 'Alexander and the Terrible, No Good, Very Bad Day' as well as the Adam Sandler comedy 'Blended.' She will next be seen in the thrillers 'Blue Sky' and 'Amityville: The Awakening.'
