Celebrating her 22nd birthday with style yet without her many pals, Selena Gomez headed out to a restaurant and night club in Saint Tropez with Cara Delevingne. Arriving on a speed board from her chartered yacht, Selena was dressed to party in a figure hugging black halter neck dress which feel above her knees and featured lace panels. Paired with the look were studded Brian Atwood pumps, while her hair was wavy and loose. Cara opted for a sexier style, and wore a sheer black blouse which showed off her black bra, with a leather look skirt and black booties.
