Madonna, eat your heart out! Naomi Campbell's taken the S&M-themed dressing to another level with this revealing strappy leather ensemble.
Naomi worked a 20s-style fringed short bob hairdo, adding a chic contrast to the sexy dress.
His foundation helps raise money for pre-school programmes for impoverished children in his native Serbia.
Robert DeNiro, Kate Hudson, Goldie Hawn and Harvey Weinstein are chairs of the event, so the guest list was, unsurprisingly, A-list.
As well as Naomi, a host of other models descended on the bash, including Karlie Kloss, Candice Swanepoel, Adriana Lima, Karolina Kurkova, and Leo DiCaprio's girlfriend, Toni Garn.
Other attendees included Camila Alves, Nicky Hilton and Lady Victoria Hervey.
But it was Naomi who was doing most of the head-turning in THAT dress.
