Among the guests at the party that Bensoni designers Sonia Yoon and Benjamin Channing threw last night at their SoHo studio were none other than Scout and Tallulah Belle Willis. While the sisters admitted they didn't know very much about Bensoni, they were, of course, familiar with our July cover subjects: their father, Bruce, and his new wife, Emma.

We couldn't help but ask—had they seen the racy Steven Klein spread? Yes, they told us. Bruce showed it to Scout, 17, and Tallulah, 15, himself. And if their reaction to seeing their father blind-folded in briefs and their step-mother's bare breasts is any indication, the girls are remarkably well-adjusted, if not a little jaded. "We think it's beautiful," said Scout before qualifying that statement. "It's funny because people keep asking us if they're like that all the time—like, whoa, kinky. And I'm like, 'It's an art editorial.'"
