Kristen Bell and Dax Shepard are so perfect together [1], we almost can't stand it. The Ranch actor celebrated his birthday on The Ellen DeGeneres Show [2] on Thursday, and ended up getting a cute surprise from his wife [3]. While giving members of the audience advice as Dr. Dax, Kristen asked what would be a good gift to get a spouse on their birthday. After making a joke about their sex life, Dax replied with a truly heartfelt answer that left both of them in tears. Honestly, you might end up tearing up as well.
