No, things haven’t gotten so bad for Jordin Sparks that she’s resorted to violence!

The sixth season winner of American Idol is guest-starring in this Wednesday’s episode of CBS’ CSI as a respected high school teacher.

When we first see her, however, she’s just a crazed woman running out of a motel room, covered in blood. Check out her lethal weapon of choice!

Sparks starred last year in the motion picture Sparkle opposite the late Whitney Houston. In 2007, she became the youngest winner in Idol’s history to take the top prize. She was 17.
