Showrunner Erica Messer has confirmed that the 47-year-old actress has now been made permanent on the CBS drama's 12th season, according to The Hollywood Reporter.
"We're all so excited to have Paget with us full-time. The BAU family has definitely missed her, on screen and off. Having her back on set has been great, it's like she never left," Messer said.
Brewster originally starred on "Criminal Minds" for five years, before stepping away in 2012.
