"Dr. Quinn, Medicine Woman" star Seymour will play Dotty, Karey's mother, who's described as "self-centered, theatrical and often inappropriate."
Seymour has recently had guest spots on "Ben and Kate" and "Franklin & Bash."
"Men of a Certain Age" alum Majandra Delfino has also been cast in the pilot as Karey's sister Penny, a self-centered, clueless singer-songwriter with questionable taste.
"Last Man Standing"'s Shawn Levy is executive producing the pilot, along with Marty Adelstein and Becky Clements. 20th Century Fox Television and 21 Laps/Adelstein are producing.
