Lena Dunham of 'Girls' is working on new HBO show: Report

"Girls" creator Lena Dunham is working on a second NYC-based comedy with HBO.

Dunham and her "Girls" producer Jenni Konner are teaming up for a series called "All Dressed Up And Everywhere To Go,"  according to Deadline.com. The show -- yet to be officially announced by HBO -- is based on Bergdorf Goodman personal shopper Betty Halbreich’s memoir of the same name.

Halbreich’s 37 years as a personal shopper for the rich and famous have made her a “New York institution,” and put her in contact with generations of stars. (You can see her work in the costume design for "Sex and the City," as well as Woody Allen’s early films.)

The new show, which has no release date, would see Dunham explore Halbreich’s life among Manhattan’s high society.

Meanwhile, Dunham's main gig "Girls" was picked up for a third season.
