Margot Robbie turned heads at the Paris Fashion Week while attending the Chanel show — debuting a chic new bob haircut and a relaxed outfit that included loose jeans, a sheer white vest, and ballet flats. While many fans loved the new look, others online focused on Robbie’s very slim appearance, sparking speculation that she might be using popular weight-loss drugs like Ozempic. Some social media users claimed she looked dramatically thinner, while others pushed back, noting the actress has always had a naturally slender frame. Robbie became a mother in October 2024 when she welcomed a baby boy with husband Tom Ackerley.
