Even models need a break from fashion week. For a frolic-filled charity event on Saturday night, Natalia Vodianova and Karlie Kloss co-hosted the annual Naked Heart Foundation's Fund Fair, to benefit the charity that Vodianova founded which supports disabled Russian children, in London, and convinced some of the industry's top models to kick back and play games.

From bumper cars to popping balloons with darts, the luxury carnival (sponsored by Calvin Klein's Euphoria and LVMH) was a sight to behold and partly due to the photogenic brethren that graced the crowd: think Toni Garrn, Natasha Poly, Mariacarla Boscono and more. In fact, Boscono hosted a tattoo parlor at the event put together by Givenchy (ahem, designer tats!).

Vodianova, who is pregnant with her fifth (!!) child (baby daddy is partner Antoine Arnault, scion of LVMH), was clad in a red sequined minidress and showed just a hint of a bump. See more of the glamorous revelry below, and as gorgeous as the guests were, it's even more beautiful that the funds raised went to a great cause.
