Kristen Bell and Dax Shepard have one of the most solid marriages in Hollywood, but the actress admits that they are constantly working at their relationship.

"We fought a lot and I loved a dramatic exit. If I could slam a door, I felt so powerful," Bell tells Redbook magazine. "If I could get in my car and screech away, it was even better. [Shepard] said to me, 'If we have an issue, you can't leave. We're going to talk or I'm not going to do this with you.' I loved him so much that I was like, 'I better get my act together.'"

The 35-year-old actress also confesses that being working parents to two daughters doesn't lend itself to a lot of spontaneity in the bedroom -- but they always find time. "We're pretty decent about staying on top of it," she says. "We'll be like, 'Okay, it's been how many days?' We find a night when nobody is coming over and we don't have to work super-early in the morning, and then we slot it in."

Bell even says that her husband gets jealous now and again. "He layers it in comedy," she shares. "When I get ready for a red-carpet event, he'll say, 'Don't get too confident tonight and think of leaving me!' I'm like, 'You're lucky that nobody at this party is going to be as interesting as you are!'"

But there's one thing that always brings this A-list couple back together, and that's "Game of Thrones." "He would rather I sleep with another man [than watch 'Game of Thrones' without him], I swear to God!" she quips.

Bell stars in "Bad Moms," hitting theaters July 29, and reveals to Redbook what surprised her most about being a working mother. "I don't let myself feel guilty about not committing to things anymore," she says. "How I position it in my head is that I have more of an obligation to my daughters than I do to anybody else."

She also stresses the importance of "being real" with her fans. "In the age of social media, when you can edit your life in beautiful pictures, it's important to remind moms that all of us are wearing yogurt and all of our hands smell like urine," she adds "When you present an unrealistic idea of perfection to people, it's not fair."

Bell gave some sage advice for all the mothers out there when chatting with ET. "Don't beat yourself up if you feel you've chosen wrong," she shared. "That's the key part of it. Don't beat yourself up."
