"I haven't thought about it yet!" the Scream star, 57, tells PEOPLE in this week's cover story of her daughter Coco, 17 (with ex-husband David Arquette). "I haven't even registered that she's not going to be here. But also, she's not here that often—let's be clear. She is out and about. This is not a girl to sit at home, and if she is, she's in her room, door shut." When it comes to motherhood, Cox, who is launching her new home-care product line, Homecourt, gives credit to her own mom (also named Courteney, who died in December 2020) for being a role model.

"But I'm not always good with boundaries. I get worn out. You've got to pick your battles and decide what is important." For Cox, the best part about co-parenting with Arquette has been "when you don't fight about things," she says. Courteney Cox (L) and daughter Coco in 2017.

There's never been a contention about stuff like that. And I think that's really, really important." Peggy Sirota Now that Coco is a teen, Cox all the more appreciates the time they spend together. "I think she's funny, and I love hanging out with her," she says. "I love when she needs me. She's fun. And you could never be mad at her, ever, for too long. Coco's a really good apologizer.
