Two-time Golden Globe winner Valerie Bertinelli ("One Day at a Time") is returning to the world of sitcoms. She has just signed to star in a new comedy pilot for TBS from writer/executive producer Dave Caplan, whose credits include TBS's highly popular sitcom The Bill Engvall Show, as well as George Lopez and The Drew Carey Show.

The as-yet-untitled sitcom centers on a single mother trying to run a business while raising two children. The premise of the show is inspired by events in Caplan's own life.

"Valerie Bertinelli became a popular fixture on television playing one of two children being raised by a single working mother," said Michael Wright, senior vice president in charge of the Content Creation Group for TBS, TNT and Turner Classic Movies. "Now she's exploring that world from the opposite angle, playing a single working mother raising two children. Between Valerie's comic skills and Dave Caplan's highly relatable humor, we're very excited to watch this pilot take shape."

The Caplan project follows the life of a woman who manages to get through the day with surprisingly good humor despite very difficult circumstances: Her husband walks out, leaving her with two kids and a struggling lumberyard. It will take every ounce of energy she has to keep both her household and her business afloat, while facing obstacles at every turn.
