In the revival of the show, which will air on Disney+, Lizzie is a 30-year-old millennial navigating life in Manhattan.
The original series was one of the Disney Channel’s biggest hits and spawned a spin-off movie in 2003.
As with the Noughties show, the reboot will include an animated version of a young Lizzie who gives revealing commentary on what she is really thinking.
Duff shared an Instagram picture of herself on the first day of production, with the caption: “Happy first LIZZIE day!!!!! NYC…..cue the rain.”

Duff is also a series regular on the comedy show Younger, which was recently renewed for a seventh season.
