With her ripped lace, dirty denim, and tattoo of her agent's name on her upper thigh, Peaches Geldof admits that she's not exactly a refined young woman the majority of the time. "But for these guys? I thought I had better clean up," said the bedazzled and updo'ed rock progeny from her perch behind the DJ decks at Bulgari's 125th anniversary celebration in London last night. "This is quite a posh crowd!" She wasn't kidding. Geldof was joined by the likes of Lady Helen Taylor, Laura Bailey, and host Alexandra Shulman, British Vogue's editor in chief. Also looking polished was none other than Princess Michael of Kent. She traveled with a bodyguard who kept everyone at arm's length—quite the nuisance during the evening's live performance by Razorlight.

In addition to the jeweler's birthday, the night also celebrated a collection of rings and necklace pendants created to support Save the Children. Images from the line's star-studded campaign lined the walls of the Saatchi Gallery, and the pieces will be auctioned off for the charity. "It's important for a luxury label to be aware of what's around us, and to look forward," said Francesco Trapani, Bulgari's CEO. "Or, as Save the Children likes to say, to help rewrite the future."
