SIENNA MILLER, DESIGNER: Sienna Miller is set to capitalize on her flair for fashion. The actress, currently the face of denim brand Pepe Jeans London, will develop her own capsule collection for the Madrid-based brand for the fall 2007 season. A Pepe spokesman declined to say how involved Miller would be in the design process, or what the collection will consist of. In January, Pepe hired Miller to be the brand’s face, and the actress is under contract through the spring 2008 season.

DESIGNS ON LONDON: Milla Jovovich may be a celebrity, but for the model, actress, singer and clothing designer, spotting women in one of her Jovovich-Hawk dresses provides the biggest thrill of all. “When I come here and see our dresses on girls, it’s like ‘Oh my God! She’s wearing the dress! She’s wearing the dress!'” said Jovovich at the launch of the collection she designs with Carmen Hawk at London’s Harvey Nichols. The duo hobnobbed with an artsy crowd at the store’s Fifth Floor Café, which — in a tribute to the American designers — had been turned into a Studio 54-themed disco for the night. Guests, who included stylist Katie Grand and artist Dinos Chapman, sipped pink champagne and apple and cranberry martinis while a DJ spun Seventies disco hits.

ROCKING THE SLOPES: For Rocawear’s “We Run the Strip” ad campaign, company co-founder Shawn “Jay-Z” Carter wooed supermodel Naomi Campbell to Aspen, Colo., where the final leg of the three-part campaign was shot over the weekend. Joining Campbell and Carter in the ads are model Jaime King, hip-hop artist Freeway and Kansas City Chiefs’ running back Larry Johnson. Mark Seliger photographed the motley crew on location in log cabins and on the slopes, as the fall Rocawear collection has an après-ski theme. The ads will hit magazines including Elle, Teen Vogue and Vibe in August.

GETTING READY: Gucci rolled out the red carpet at its Fifth Avenue flagship Thursday night to prep partiers for the annual Museum of Modern Art Party in the Garden. Event co-chairs Jo Carole Lauder and Agnes Gund feted the museum’s Junior Associates, including Aerin Lauder and Renee Rockefeller. Guests roamed the four-story store, checking out shoes and ooh-ing over dresses, perhaps even eyeing a few to don for the June 6 bash, which is sponsored by the fashion house.
