According to Kristen Bell, firm butt cheeks are her "favorite things on the planet!"
"I want to round cupcakes, always. I kicked my buns and abs sets into high gear when I knew I'd have to be in my bra and underwear on House of Lies," the 31-year-old actress tells the April issue of Women's Health. "But I don't show my crack! All the Mr. Skins of the world are like, 'Ooh, Kristen gets naked!' I'm like, 'Dream on!'"
The actress' costar Don Cheadle, however, does reveal his glutes on camera. "If you had those beautiful chocolate bun-cakes, you'd show 'em too!" Bell jokes. "Let's be honest."
Bell shows noticeably less skin in her upcoming comedy Outrun, which is directed by her fiance of two years Dax Sehpard, 37. Working with her live-in love presented a new set of challenges for the actress.
"I would watch him walk back to the monitor and yell things such as 'Action!' or 'Cut!' and I'd just go, 'And you expect me to work when you're doing cute things around me all day? How am I supposed to focus?'"
Bell and Shepard "nauseate ourselves with how mushy we are," but they're not concerned with legally tying the knot. Instead, the A-list duo jokingly partnered up with Shepard's best friends.
"We decided to create the first four-way marriage," Bell tells Women's Health, "where our couple has married their couple."
