In one scene from their new show, Up All Night, Christina and Will curse in front of their baby — which they've accidentally done in front of their own children.

"I think we did that until all of a sudden your baby goes, 'F***!' And then you’re like, Awww, s***,' " Christina explained to New York Magazine.

"Yeah, our eldest son is almost 3, and now they hear everything. It’s like living East Berlin in the seventies. So you have to be really, really careful," Will agreed. "Christina and I talked about this, but there are things in the pilot that are really accurate. Since the pilot, we find ourselves in situations where it’s like, 'Wow, not only is this real, but we actually did this in the pilot. This is so strange.' Like arguing about who stayed up more the night before. If your baby is up, that’s such a real conversation about, 'I was up for these hours.' "

And Christina has done the same in her household.

"And then what’s even geekier about it is that both people stop and go, 'Oh my God, this is so from the pilot. Are we doing the pilot right now?' " she recalled. " 'The pilot is happening right inside my house.' "
