Kristen Bell Shares How Her Marriage To Dax Shepard Works Despite Being 'Polar Opposites'

Kristen Bell and Dax Shepard have personalities that are the extreme opposite of each other, but they have worked to find a middle ground in married life. In Bell's words, "A recipe is not delicious with one ingredient."

Bell spoke about her nine years of marriage to fellow actor Shepard on Tuesday's segment of CBS Mornings. "Dax and I are polar opposites and the solution is always in the middle. You have to have diverse points of view," she told the hosts.

Though this life lesson is something she learned from her marriage, it is also something she applies to several different aspects of her life, including the second installment of her “My Purple World” book series she co-authors with Benjamin Hart.

"A lot of different brands work on kindness with kids. We wanted to be slightly more specific. So what if there were a set of principles? Ours are, you need to laugh a lot, you need to work hard, you need to ask great questions -- both big and small -- and you need to use your voice but also listen, and just be you. We like to say, you're the only you we've got," Bell explained.

Bell and Hart's first book, "The World Needs More Purple People," is all about a person who can see beyond red and blue, realize the world is a mix of both, and becomes a purple person, per ET Online.

Now, the sequel, "The World Needs More Purple Schools" is a "logical next step. It's really a giant love letter to educators who have dealt with so much on the front lines these last couple of years," she explained.

Meanwhile, she and her husband are also trying to become better people, added Bell. The couple recently announced a new podcast, "The Honey and the Hammer," which gives listeners a peek into her and Shephard's bedroom conversations.

"We're always talking about how hard it is to be human. Everybody's got a different point of view, it's hard to get along sometimes," she said.

Bell says that the idea for their new podcast struck when Shepard placed a microphone on their bedside table one evening, as they bantered. They are taking relationship questions from Shepard's "Armchair Expert" podcast audience and answering them together.

"Our goal is to allow people to vent," she said, "and then encourage them to say 'ok what do you think your side of the street is?'"
