A 20th Century Fox rep confirms to The Hollywood Reporter that the It's Always Sunny in Philadelphia and Perfect Couples actress will reprise the role of Nick's (Jake Johnson) manipulative ex-girlfriend Caroline for the last three episodes of the season.
Her appearances will coincide with the ex-centric "Backslide," the season's penultimate episode, which also brings back Jess' (Zooey Deschanel) brief boyfriend Paul (Long).

Ellis previously appeared in the New Girl pilot and "Wedding." Caroline's cameos have coincided (and prompted) rather dramatic emotional responses from Nick.
Before she heads back to New Girl, Ellis will also stop by the March 28 episode of Happy Endings. She's repped by CAA.
