That same evening, Rihanna was spotted rocking a Louis Vuitton Barack Obama t-shirt as she made her way out of My Studio nightclub after a night out in Hollywood.

Rihanna is wearing a Chanel necklace in the shoot. Perhaps that is a clue to the secret campaign?

FYI: Ri is wearing a Pyer Moss jacket.
