British actress and model Rosie Huntington-Whiteley has modelled for the likes of Burberry, starred in Transformers: Dark of the Moon and, most recently, snagged a role in George Miller’s coming Mad Max Fury Road. The 27-year-old was in Australia last week as an ambassador for ModelCo to launch its natural skincare collection. She talked to me about landing the Mad Max role and what’s off limits when it comes to social media.
