Angela Kinsey, Eva Amurri, Max Greenfield

Angela Kinsey and  Eva Amurri will be stirring up trouble on New Girl this year!

The Office alum and the Californication actress will both pop up in the second episode of Season 3 to spar with Jess (Zooey Deschanel) and Schmidt (Max Greenfield), TVGuide.com has learned exclusively.

Kinsey will play Rose, a snobbish "cool" teacher whom Jess meets at the school where she landed the substitute teacher gig last season. Rose is turned off by Jess' diligence and goody-two-shoes approach to her job.

"She's struggling with the politics," executive producer Liz Meriwether says of Jess' new job. "At the school, there's some mean girl teachers that don't like her there, and she's trying to find her place at the new school and see if she can turn it into a permanent position."

Meanwhile, Amurri will reprise her role as Schmidt's competitive co-worker Beth, who will cause trouble in his love life. Don't worry, they're not turning this into a love quadrangle. The third season will pick up moments after Schmidt ran away from both Cece (Hannah Simone) and Elizabeth (Merritt Wever), who will be back for an arc this season. But don't assume that just because Elizabeth is only sticking around for a few episodes, Schmidt ultimately picks Cece.

"It's a little more complicated than that," Meriwether says. "It's a choice that he's still struggling with in the premiere. He genuinely cares about both women and he's just so confused about what to do. He's forced to take desperate measures to figure it out. He potentially does some things that are not good." We hear those things may include juggling both women, which Beth schemes to expose when she pops back up.

New Girl returns Tuesday, Sept. 17 at 9/8c on Fox.
