Dax Shepard has no problem poking fun at his wife, Kristen Bell. The 46-year-old actor filmed 40-year-old Bell trying out cryotherapy on Wednesday. For the process of exposing her body to subzero temperatures, the mother of two rocked a purple bikini, sweatband, boots and mittens. «You look like a Bond villain girl? One of the two,» Shepard quipped to his wife from off camera.
