In the "50 Ways to Heave Your Mother" episode of the ABC Family show, Shirley guest stars as David and Patrick Cassidy's mother -- Patrick is her biological son – when she visits the boys and meets David's long-lost daughter for the first time. She insists that Ruby (Alexa Vega) call her Mrs. Gallagher instead of Grandma -- even as Ruby valiantly tries to win her affections.
"Ruby and the Rockits" is a family affair as Shaun Cassidy serves as exec producer and brother Ryan is the set decorator.
"50 Ways to Heave Your Mother" airs Tuesday, September 15 at 8:30 p.m. on ABC Family.
