Megan Fox begins her five-episode guest-starring arc on New Girl Tuesday as Reagan, a pharmaceutical sales rep who rents Jess' room while Jess is sequestered on jury duty (aka Zooey Deschanel is on maternity leave). In many ways, she's the anti-Jess: confidently sexy, emotionally reserved, and not interested in getting involved in roommate drama with the guys and Cece (Hannah Simone). Which is kind of a problem, because her presence creates all kinds of issues in the loft.

"She travels a lot, so she doesn't usually get involved with a group of people like this," New Girl creator Liz Meriwether tells TVGuide.com. "She poses a problem for a lot of the characters in a really funny way."

Reagan affects everyone differently: Schmidt (Max Greenfield) is intimidated by her history with Cece, Nick (Jake Johnson) turns into a babbling lunatic who completely forgets how to act like a person, and Cece suffers from Nick's strange behavior. Winston (Lamorne Morris), however, is impervious to her hotness, and his relationship with Reagan develops in an interesting way.

But while Reagan seems perfect in her first episode, it doesn't take long for her flaws to emerge — one of which is that she has a somewhat gross way to eat a burrito. Oh, and also? She might be a criminal.
