Rihanna and her stylist Mel Ottenberg attended the Chanel couture show in Paris earlier today at (where else?) the Grand Palais. RiRi is currently in Europe on her “Diamonds World Tour” and performs in Berlin, Germany tonight, but obvi couldn’t resist a little Chanel time. (What a day!) Joining her front row were Kristen Stewart, Michael Pitt, Milla Jovovich, Vanessa Paradis, Rose Byrne, and Bobby Cannavale.
