She seems to spend all her time hitting the gym if her Instagram page is anything to go by, however all Millie Mackintosh's hard work proved to be paying off when she stepped out on Thursday.
Showing off her enviable pins, the former Made in Chelsea star looked stunning as arrived at the Fashion Targets Breast Cancer 2014 event, with guests including singer Eliza Doolittle.
Despite opting for an all-black look, the fitness fanatic was in no way overshadowed by the other guests in her tiny shorts at London's St Pancras Renaissance Hotel.

Millie's teamed her bottoms with a low-cut strappy top, tuxedo jacket and skyscraper heels, while her hair was curled into soft waves.

Founded by Ralph Lauren two years ago, Fashion Targets Breast Cancer aims to unite the world of fashion against the disease, by raising money through a number of key items.
