Although an NBC rep declined to comment, sources close to The Office confirm to TVLine exclusively that Catherine Tate is poised to return for the show’s upcoming ninth season as a full-fledged series regular.

Tate’s boss lady Nellie initially received a somewhat chilly reception from her colleagues at Dunder Mifflin’s Scranton branch. But by season’s end, the character’s redemption was in full swing as she formed bonds with the likes of Pam and Darryl. In the finale, she even enjoyed a warm moment with Andy after he reclaimed his post as manager (presumably making her his No. 2).

Tate’s return means that all major Office castmembers will be back in the fall with the exception of Mindy Kaling, who is headlining The Mindy Project on Fox. Several new faces are expected to be introduced as well as the long-running comedy undergoes a mini-reboot.
