Ex marks the spot for Breaking Bad's Betsy Brandt, who has been cast as the former wife of Hank Rizzoli (Ray Romano) on Parenthood, TVGuide.com has learned.

Parenthood video: Ray Romano and Lauren Graham on Hank and Sarah's "interesting chemistry"

Fans first learned about Hank's past when his hard-to-please teenage daughter Ruby came to visit. After Sarah (Lauren Graham) won Ruby over by fake-cropping her into a picture with Justin Bieber, she won Hank over as well: He kissed his (newly engaged, we might add) assistant in the most recent episode. How much trouble could his ex stir up?

Parenthood airs Tuesdays at 10/9c on NBC.
