Taylor Swift guest starred on a recent episode of CSI. And what does the teen sensation think of acting?  Well, Taylor was very passionate about her role and the cast and the crew.  Was it passionate in a good way or a bad?

Taylor gushed about performing, actually.  This is what she told People Magazine:

Calling the experience “life-changing,” she continues, “Ah, I can see it now. ‘You know, when I was a youngster, I got to guest star on CSI!’ It was marvelous! So marvelous, it was!”

Swift, 19, will play a teenage girl whose family runs a motel in Las Vegas. No air date has been confirmed for her guest appearance.

I’ve actually scene stills of the shooting and you wouldn’t even guess it was Taylor!  She looks shocking.  Well, not shocking but shockingly different.  She is a brunette!!
