The "Cougar Town" actress tells Ellen Degeneres on "The Ellen Show" that she, Arquette, their daughter Coco, and Arquette's pregnant girlfriend Christina McLarty all had dinner together recently.

Coco is excited to become a big sister to Arquette and McLarty's baby boy, Cox tells Degeneres. "At first she was nervous because, you know, it's a big deal.  At first, I was nervous, I was like woo, heavy," she says. "Now it's great and we actually all had dinner the other night. The whole family. It's a very unique relationship. All of us -- like, literally, me and Christina and David and Coco. It's great though."

Cox also describes how much fun she had on vacation in Mexico with a seemingly random group of people: pal Jennifer Aniston and fiance Justin Theroux, Howard Stern and wife Beth Ostrosky, and Jimmy Kimmel and wife Molly McNearney.
