"The retouching that was done to the photograph was only done to resolve some distortion with using a wide angle lens for a group shot, and not to alter or modify anyone's face," they said in a statement to PEOPLE. "We used a wide angle lens, and it might've made Rumer's chin look smaller from the higher angle that we shot the image."
"We did correct for the optics of the lens slightly as people's heads get distorted through the wide angle lens. We certainly did not intend to change the way she naturally looks. Our intention was to capture the special bond between Rumer and her sisters."
Any friends of fans of mine who posted this I would appreciate if you took it down. The photographer Photoshopped my face to make my jaw smaller and I find it really offensive for anyone to try and change the way you look so drastically. I love the way I look and I won't support anyone who would feel a need to change the way I look to make me beautiful. Whether or not they realize it, it is a form of bullying, which I won't stand for.
"It saddens us that Rumer feels the way she does about the image and hope she understands that there was never any intention with it to alter her appearance."
Willis posted on Instagram Tuesday that she believes Williams and Hirakawa photoshopped the image.
"Any friends of fans of mine who posted this, I would appreciate if you took it down," Willis, 27, wrote. "The photographer Photoshopped my face to make my jaw smaller and I find it really offensive for anyone to try and change the way you look so drastically."
