Jennifer Love Hewitt has joined the cast of CBS’ “Criminal Minds” as a series regular. Her character will be introduced in the crime series’ 10th season premiere this fall.

Hewitt will play Kate Callahan, a seasoned undercover agent whose work at the FBI has landed her a position within the Behavioral Analysis Unit.

“We’re thrilled to introduce a new special agent by adding the very talented Jennifer Love Hewitt to our amazing cast,” said Erica Messer, showrunner and executive producer of the series. “Many of us on the show have enjoyed working with her over the years and look forward to again. We have exciting storylines planned for her character and the entire BAU team as we head into our 10th season.”

Hewitt previously starred for five seasons on “Ghost Whisperer” for the Eye. Her other television credits include “The Client List,” for which she earned a Golden Globe nomination, “The Lost Valentine” opposite Betty White and “Party of Five.”

The next season of “Criminal Minds” will bow Oct. 1 at 9 p.m. on CBS.
