Did Vogue Russia Photoshop Off This Model's Arm?

It's been a bad month for models' limbs in Vogue. First, Doutzen Kroes lost one of her legs to Vogue China. Now, some people think that the model Natasha Poly is missing an arm on the new cover of Vogue Russia. Maybe it's just behind her head? Either way, it looks funny. In any case, Coco Rocha, herself no stranger to Photoshop-related controversies, just Tweeted, "Hey, photoshop guys! Can you please be sure to count two arms and two legs on the girls you cut and paste? Thanks!! Sincerely, Models."
