She had wowed Venice earlier in the day, bringing high-octane glamour to the red carpet in a gorgeous pale pink miniskirt ensemble.

Fresh from a Mediterranean cruise with her boyfriend, actor Gad Elmaleh, the 26-year-old looked radiant and sun-kissed as she attended the Gucci Award for Women in Cinema in the Italian city.
She was joined by actress Salma Hayek, who was equally glamorous, showing off her hourglass curves in a black, capped sleeved number with a plunging neckline.
It was an important event for the actress, whose husband Francois-Henri Pinault is the chief executive officer of PPR, the parent company that owns Gucci amongst other high-profile designer brands.
The Gucci Award for Women in Cinema went to film editor Thelma Schoonmaker and was presented by Frida Giannini, creative director at the Italian fashion house.
