According to Deadline, Patrick Sabongui has now joined the cast in a recurring role.
The actor will play a slick city landlord called Martin, who has a run-in with Carl Gallagher (Ethan Cutkosky).
Sabongui portrayed Professor Chad Wiley in the first season of Firefly Lane.
The series, starring Katherine Heigl and Sarah Chalke, dropped on Netflix earlier this year and has yet to be officially commissioned for a second run, despite a cliffhanger ending which perfectly sets up a potential second season.
His casting follows the final Shameless season also adding Chelsea Alden to its cast.
The actress played Mackenzie in the latter seasons of 13 Reasons Why.
She appears in the final Shameless run as a furniture store cashier named Tish, who crosses paths with Carl after he rescues her from a furious customer.
Shameless season 11 airs on Showtime in the US.
