The Griswolds are getting incestuous!

Juliette Lewis revealed that she is joining "The Conners," ABC's "Roseanne" spinoff. Johnny Galecki is also returning as David. They will play a couple, with Lewis playing David's girlfriend Blue, who was (insultingly) referenced by Darlene (Sara Gilbert) in the "Roseanne" revival last year.

As Lewis noted with her post on the news, this will mark a reunion for her and Galecki after playing siblings Audrey and Russ Griswold in the 1989 movie "National Lampoon’s Christmas Vacation."

"The Conners" will also bring back John Goodman, Laurie Metcalf, Lecy Goranson, Michael Fishman, and Emma Kenney. Roseanne Barr was fired, leading to the end of "Roseanne," and she revealed that "The Conners" plans to kill off Roseanne Conner with an opioid overdose.

"The Conners" premieres Tuesday, October 16 on ABC.
