Jennifer Love Hewitt is headed back to CBS.

The former Ghost Whisperer star has been cast as a series regular on Criminal Minds Season 10, the network confirmed today via press release.

She will come on board as Kate Callahan, a veteran undercover agent whose outstanding work at the FBI has enabled her to nab a position with the Behavioral Analysis Unit.

We'll first meet Callahan on the October 1 season premiere.

"We’re thrilled to introduce a new special agent by adding the very talented Jennifer Love Hewitt to our amazing cast,” says showrunner Erica Messer. “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 essentially takes over for Jeanne Tripplehorn, whose Alex Blake exited the series on the Criminal Minds Season 9 finale.
