Jeanne Tripplehorn is joining Criminal Minds as a series regular, CBS announced. Minds is heading into its eighth season, and Tripplehorn will play an FBI profiler, taking over for Paget Brewster, who left the show at the end of this past season. It's tough to believe 13 million people watch this show every week, but they totally do.
