Tina Fey, Robert Carlock working on another NBC comedy series

Emmy Award-winners and producing partners Tina Fey and Robert Carlock are returning to NBC with a pilot-production order for an untitled comedy written by Tracey Wigfield.

The potential series focuses on a mother-daughter relationship that is "challenged when an overly involved New Jersey mom gets an internship at her daughter's workplace, a cable news network," a synopsis said.

"Tina and Robert are two of the pre-eminent voices in comedy, and we couldn't be more thrilled that they're bringing their next project to NBC," Jennifer Salke, president of NBC Entertainment, said in a statement Thursday. "We also adore Tracey, who has written some brilliant episodes of both 30 Rock and The Mindy Project. With this super-talented trio at the helm, we're eagerly looking forward to their next great show."

Fey and Carlock were writers and producers on NBC's 30 Rock, which ran for seven seasons and won the Emmy three times as best comedy series. Fey also won two Emmys as a writer on 30 Rock and one as a member of the writing staff for Saturday Night Live.

Wigfield won an Emmy for penning the series finale episode of 30 Rock with Fey. Wigfield is currently a writer and producer on Universal Television's The Mindy Project,
