Love is . . . doing things that are sometimes gross but necessary, right?

Just ask Kristen Bell, who loves husband Dax Shepard so much she agreed to prep him for a scene in This is Where I Leave You.

“She’s the only person I would feel — I didn’t even feel comfortable with her doing it. It was a terrible experience,” Shepard told Conan O’Brien Monday night.

“While she was trimming it she was humming,” he added.

Shepard, who has a nude scene in the star-studded dramedy, also revealed his exercise regiment leading up to the film shoot.

“I don’t want to put you in a box on this but I do think we both suffer from tall white guy syndrome, where your back just goes into your legs,” he told Conan. “There’s really no buttcheeks there . . . I spent a lot of time just doing lunges and squats because I knew they were going to be on full display.”

This is Where I Leave You is in theaters now. Watch the full Conan interview, below.
