Under carnival lights guests like Tinie Tempah, Jourdan Dunn, Lily Donaldson and Nicholas Hoult joined ringmasters Natalia Vodinova and Karlie Kloss for London's second annual Naked Heart Foundation's Fund Fair.

Here's what we loved...

Karlie Kloss's #LikeABoss Suit...

The supermodel was the coolest ringmaster in a black co-ord suit with floral embroidery detail. From Stella McCartney's current Spring 16 collection we also loved how Kloss perfectly matched her lippy to the suit's poppy floral motif colour. Meanwhile, co-host Natalia Vodianova who is pregnant with her fifth child showed just a hint of a bump in a dazzling customised red minidress from Calvin Klein. 

The Amazing Stalls (And Mega Prizes)...

Natasha Poly was in charge of the Repossi Hook-a-Duck pool, Arizona Muse kept the Louis Vuitton pop-a-balloon challenge stall in order (hey, when there's LV prizes to be won things can get rowdy) while milliner Stephen Jones held a ping-pong game where he rewarded lucky winners with his signature hats. Elsewhere, Ulyana Sergeenko served up traditional Russian bilinis to hungry guests, Millie Mackintosh supervised the Dom Pérignon Champagne Hoopla stand and Erin O'Connor ran the Dior Treasure Island hunt where partygoers dug (some very frantically and all sans shoes) through sand to find hidden keys that unlocked the doors of minature beach huts housing Dior treats. 

The Dodgems...

Yep, there was even a full on bumper cars arena that guests including Tinie Tempah, Lily Donaldson, Jamie Campbell Bower plus Pixie Lott and her boyfriend Oliver Cheshire couldn't resist taking a spin in. 

The Epic Wheel Of Fortune...

This is where Vodianova and Kloss where mainly hanging out, persuading guests to spend £50,000 in the hope of landing on some pretty amazing prizes. These included Oscar party invites, VIP front row seats to the Victoria's Secret Fashion Show and lunch with Vodianova and Mr. Valentino at his own home. Talk about once in a lifetime opportunity! 

The End Result...

With last year’s event raising more than £347,000 for the Naked Heart Foundation, the stakes were even higher for round two. Half way through the night the figure stood at £600,000 pounds. A couple of hours later, the final total amount was totted up. The result? An incredible £850,000 which all will go towards the charity’s programmes to develop a network of support services for families raising children with special needs and to create inclusive play facilities for children of all abilities.
