Former 'Criminal Minds' star AJ Cook has agreed a deal to return to the crime drama series full-time.
Deadline.com reports that Cook has signed a two-year deal to reprise her role as Special Agent Jennifer 'JJ' Jareau.
The website says that she will guest star in the final episode of the current season, which airs on American television on 18 May.
She will then return to the show full-time in the autumn.
There was widespread anger among fans of the show when the makers of 'Criminal Minds' decided not to pick up their option on Cook's contract at the end of the last series.
