Whether Photoshop, contouring or her constantly shrinking frame is to blame, there is no denying that Khloé, 32, looks nothing like her old self.

“Oh wow… love you @khloekardashian but in this pic I don’t recognize you,” one fan wrote while another added, “Hope this is just editing on her face and not RL.”
