Over the weekend, supe-cum-saint Natalia Vodianova staged Love Ball Riviera at Opéra de Monte Carlo, benefitting a variety of children’s groups, including her own Naked Heart Foundation . Guests — who included Bono, Karl Lagerfeld, Mario Testino, Novak Djokovich, Harvey Weinstein, and hosts Prince Albert II and Charlene, Princess of Monaco  — gathered to celebrate the fourth edition of the fundraiser and take in performances by prima ballerina Diana Vishneva, bass soloist Ildar Abdrazakov, and violinist Maxim Vengerov.

Guests also bid on auction prizes ranging from Louis Vuitton luggage and Dior couture (Natalia’s squeeze was also on hand — Antoine Arnault, son of Bernard Arnault, CEO of LVMH) to a private tennis lesson with Rafael Nadal and a Chanel internship with Karl Lagerfeld. Remember, this is Monte Carlo, and so après-auction, guests retired to the casino, where they gambled and swirled until the small hours.
