Dax Shepard and Kristen Bell may seem like a picture-perfect celebrity couple, but even they have their disagreements. During an appearance on The Ellen DeGeneres Show on Tuesday, the CHiPs actor told the host about an argument he's currently having with his wife over the awkward placement of his La-Z-Boy chair in their living room. "I'm winning the battle, I certainly won't win the war," he jokingly told Ellen. Of course, the chair is the least of their worries. Dax also explained the hilarious parenting moment he had when he accidentally swore in front of his 3-year-old daughter, Lincoln. Let's just say, it didn't end well.
