Coco Rocha has dismissed claims a Longchamp image of her was retouched.Coco Rocha has slammed claims her latest advertising campaign contains a "Photoshop fail".The model appears in luxury leather goods company Longchamp's new images alongside Emily DiDonato. The pictures have recently been revealed, with one showing Coco steering a bicycle along a cobbled path, with her legs sticking out at the side. Emily is riding along behind her, sitting on the saddle. Emily's legs are tucked up so can't be seen, as the picture was taken from the front. This caused many to speculate about whether an over-zealous touch-up job had taken place, with the model's legs accidentally removed. Coco is furious about the claims."I enjoy a good Photoshop fail as much as the next person, but when I saw blogs today... supposedly pointing out a "Photoshop disaster" in my current Longchamp campaign, I knew I had to correct them," she wrote on her Tumblr blog."Actually, as you can see in the behind-the-scenes pictures above (which were posted everywhere a few months back), she's just balancing with her feet on the seat behind me. Skillful, I know, but no Photoshop disaster this time... I believe you stand corrected!"Coco included several images - shot by Max Vadukul - taken from the side of the bike, in which Emily can be seen crouching on the cross bar.Coco has been open about her distrust of Photoshop in the past and was fuming when a bra she was wearing was airbrushed out of a cover shot used in Elle Brazil - the model famously refuses to pose nude.
