Kate Moss and Cara Delevingne are the co-stars of Burberry’s newest fragrance campaign for a scent due out in the fall. Burberry teased a behind-the-scenes-shot of the Mario Testino–shot campaign on its Instagram account this morning. Cara DeLevingne also posted the picture on her account with the caption “regram so excited to be doing a new fragrance for @burberry with the beautiful Miss Moss shot by @mariotestino watch this space … #katemoss.” Both models are wearing Burberry trenches, with Moss smiling beautifully and Delevingne fighting the irresistible urge to pull her trademark screwball face. Just think of the outtakes. The only proper reaction is this.
