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 [1], 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.
