Selena Gomez and Cara Delevingne Partied in Saint-Tropez

By

It’s been an eventful week for new friends Selena Gomez and Cara Delevingne, who appear to be joined at the hip since celebrating Selena’s 22nd birthday on a yacht on the French Riviera over the weekend. Last night, the two pals took a break from Jet Skiing, parasailing, and other water-themed activities to attend the inaugural Leonardo DiCaprio Foundation Gala in St. Tropez, where they were joined by Eli Mizrahi, Bono, and Leo himself. Meanwhile, back in New York, Rachel McAdams and Mick Jagger chummed around at the after-party for the premiere of A Most Wanted Man, and Chrissy Teigen and Rosario Dawson celebrated Belgium National Day with plenty of Stella Artois. Robbie Myers hosted a party for The Honorable Woman at the Ludlow that drew Maggie Gyllenhaal and Peter Sarsgaard, and Chanel Iman, Cleo Wade, and Martha Hunt all attended the opening of Marilyn: The Lost Photos of a Hollywood Star at Sumo in New York.
