Dax Shepard Explains in Detail Why Kristen Bell Shaved His Butt

Dax Shepard got candid on Monday's episode of Conan, opening up about his nude scene in This Is Where I Leave You and revealing his wife's role in some, well, necessary grooming habits. "It was incredibly nerve-racking," he said of the nude scene, adding, "While I don't have a lot of hair on the cheeks — they're nice — you know, there's an ample amount . . . there's a forest in the valley." Dax described in detail his "deep, deep fear" of how he might look on screen, explaining that he eventually turned to his wife, Kristen Bell, to help him shave. Bottom line? "It was a terrible experience." Watch Dax's hilarious interview above to hear the whole story, including why there was humming involved.
