Even though she was wearing pants, Winter refused to pass on a belfie opp.


Bella Thorne and Winter basically share the same belfie-loving brain.

"I have a roll where my thigh and stomach meet and that's OK," the plus-size model wrote in March. "I have a crease where my back naturally folds and that's OK. It doesn't make me any less beautiful."


Iskra Lawrence, too, posted a belfie with a cause.

"Just your lil daily reminder that respect does not = amount of clothes you wear," the model wrote on Instagram. "Respect = being human. Nuff said."


Lawrence also used a butt selfie to show some love to Christian Siriano  — a designer who's never afraid to dress booty-baring influencers.
