The Modern Family actress is set to star alongside her RL bae Dominic Sherwood on the Netflix series.
The baben' star announced via Instagram that she will be playing the role of the Seelie Queen.
"Sorry I tricked you all in to thinking I wasn't the Seelie Queen. In my defense I never lied... I was just getting in to character ;) 👑 #shadowhunters," she captioned the pic.
How ~*ethereal*~ does she look!?
Meanwhile, that red hair totes suits her. Maybe she shouldn't take that weave out when she's done?
