EYE ON THE PRIZE: Making her way backstage after the Dior show on Friday, Rihanna — wearing a red fur coat from the fall 2013 couture collection — stopped to greet fellow guests including Azzedine Alaïa, Suzy Menkes and blogger Bryan Grey Yambao, aka Bryanboy.

After embracing designer Raf Simons, Rihanna posed for photographers, letting her coat slip off seductively, even though it was already cut out at the shoulders. “I’m going to call you because I want to wear, like, 20 things on there,” Rihanna told Simons before leaving.

Almost drawing as much attention was Valérie Trierweiler, making her first public appearance in Paris since her split from French President François Hollande in the wake of the revelation in January that he was having an affair with actress Julie Gayet.

Other guests at the show included Jessica Alba, Emma Roberts and Evan Peters, Ruth Wilson, Eva Herzigova, Marisa Berenson and Harvey Weinstein.

Peters will be seen in May in “X-Men: Days of Future Past,” and said playing the character of Quicksilver required four hours a day of hair and makeup. “You just talk, hang out, play on your phone, maybe read a little bit,” he shrugged.
