Taylor Swift Filming CSI... RIGHT NOW!

Taylor Swift just twittered from the Los Angeles set of CSI: Crime Scene Investigation, saying, “on set… Transforming into someone else. I love CSI.”

The 19-year-old Nashville princess will be in an upcoming episode of the hit CBS drama playing a brunette Haley Jones, a teenage girl whose family runs a seedy Vegas motel. Over the course of a year, Haley goes through a series of changes that have tragic consequences. In one scene, Taylor rides a bicycle!
