Joey Lauren Adams is on her way to ABC Family.

The actress - best known for film roles such as Chasing Amy and Mallrats, but who also recurred as Pammy on United States of Tara - will appear on two episodes of Switched at Birth this summer. Sources confirm she will portray Nikki’s mother.

Creator Lizzy Weiss broke the casting news of herself when she tweeted a photo of Adams and Lucas Grabeel on set. The latter, of course, plays Nikki’s fiancé Toby.

Look for Adams to show up on the August 5 and August 12 installments.
