Selena Gomez arrives in Emilio Pucci then changes into Dior at Leonardo DiCaprio's Foundation Gala in Saint Tropez

Pop princess Selena Gomez continued her array of glamorous fashion looks and arrived for Leonardo DiCaprio's Foundation Gala dressed in a slinky Emilio Pucci dress. The 22 year, who is vacationing in Saint Tropez with new bff Cara Delevingne and rumored beau Tommy Chiabra, stunned in her olive Emilio Pucci Fall 2014 gown which was part draped and part embellished and featured a bold thigh slit. The sexy look was styled with gold hoop earrings and Casadei 'Barbarella' pumps in a matching hue.

As the night moved on, Selena changed into a darker look, this time opting for a Christian Dior Spring 2014 strapless frock with a black tutu. The dress featured the signature emblem from the collection, and the actress/singer completed her look with a pair of black pumps, a veil, and a vampy burgundy lip colour.
