The ABC comedy pilot stars Ellen Woglom and Ravi Patel as a young couple who have a baby.
The duo have to deal with their parents, who come from very different cultural backgrounds and have contrasting ideas about how to raise the child.
According to Deadline, Gaffney will star in the project as the mother of Woglom's character Anna. She will appear alongside Christopher Rich, who has already signed up to play Anna's father.
Gaffney has previously worked on shows including Mad About You, That '70s Show and Absolutely Fabulous.
