The "Lizzie McGuire" actress will guest star on the CBS comedy as Walden's (Ashton Kutcher) girlfriend Stacey, according to TVLine.
Duff tweeted about her role on Tuesday.

But in true "Two And A Half Men" fashion, Walden will end up falling for someone else. In this case, it's Stacey's grandmother, who will be played by "Taxi" vet Marilu Henner.
Since her "Lizzie McGuire" days, Duff has guest starred on "Gossip Girl," "Community" and more.
