Jeanne Tripplehorn is joining Criminal Minds as a series regular, CBS announced Thursday.

The Big Love alum will replace Paget Brewster, who left the series this spring.

"We're thrilled to have Jeanne Tripplehorn join our team as a profiler," said executive producer Erica Messer. "Her character will be introduced in the premiere. It's an exciting way to start Season 8."

Earlier this month, Messer voiced a very different opinion, saying that she didn't want to add a new character, but CBS did. "My initial vote was that I don't want to replace her," Messer said. "I feel like the team could function without anyone else, but I'm getting a lot of other opinions that weigh in."
