If you thought being a Princess was all about puffy dresses and tea parties, Kate Middleton is here to prove you wrong. The Duchess of Cambridge was not afraid to get physical when she popped on some boxing gloves and showed her mean right hook for the launch event of Heads Together, a mental health campaign she started with her husband Will and brother-in-law Harry. The charity aims to help end the stigma around mental health issues, while promoting exercise to stimulate the mind. According to The Daily Mail, Kate's outfit retails for about $568 US dollars, but that didn't stop her from throwing a few charming, ladylike punches.
