As CSI: Crime Scene Investigation celebrates its 25th anniversary, the iconic crime drama is taking a look back at the many celebrity guest stars who appeared on the show during its 15-season run on CBS.

The series, which premiered on October 6, 2000, forever altered how viewers engaged with solving crimes and DNA analysis on television. While some stars, like Dakota Fanning, had small one-episode roles early in their careers, others were already household names by the time they graced the CSI set.

One such star was Taylor Swift, who was described by the show's toxicologist, Jon Wellner, as a "mega-fan" who was "just so happy to be there, with the perfect attitude." Wellner praised Swift's performance, saying, "If you saw the episode, she really kills it. And that's what our show is all about. We're all working together to make a great show."
