Allison Janey Cast in Chuck Lorre/Anna Faris Sitcom

CBS might as well green light Mom for series right now.

The upcoming pilot, already starring Anna Faris as a newly sober/single mother in Napa Valley, has now cast Emmy winner Allison Janey. She will come on board as Bonnie, the less-than-ideal mother to Faris' Christy.

Forever C.J. Cregg to fans of The West Wing, Janney has since appeared in episodes of Lost, The Big C and Mr. Sunshine.

Oh, Mom is also produced by Chuck Lorre. You can book it for the fall schedule.
