Anna Faris and Allison Janney Anna Faris and Allison Janney

Christy (Anna Faris) has fallen head over heels for David (Nick Zano) on CBS' Mom — but her home life is also starting to get turned upside down as a result of the new romance.

TV Couples: Should they or shouldn't they?

On Monday's episode, Christy calls out of work and forgets her daughter Violet's (Sadie Calvano) Lamaze class because she's spending time with her new beau instead. Luckily, she has her mom Bonnie (Allison Janney) to pick up the slack and pinch-hit in the Lamaze class — even if she does think it sounds like "Japanese porn." And Bonnie certainly knows a thing or two about putting relationships ahead of her family!

Mom airs Mondays at 9:30/8:30c on CBS.
