This weekend Riccardo Tisci, BFF to Kanye and wedding dress designer to Kim, turned 40 and he did it with a group of his closest, most famous friends. Reading like a veritable who's who of pop culture —with Puff Daddy, Kanye, Cassie, Justin Beiber to name a few— the crème de la crème of fashion and entertainment gathered on the party island of Ibiza in the Givenchy creative director's honor. The Studio 54-themed all-black party yielded some of the most unforgettable Instagrams of the year. Just imagining all the supermodels, Oscar winners and the entire Kardashian Klan running around in an intoxicated frenzy was enough to make our heads spin. And as if the night couldn't get any more legendary, the designer was serenated by Naomi Campbell and Kate Moss, who gifted Tisci with a pair of 24karat gold Beats headphones. We all know the best gifts are the ones that money can't buy, so thankfully there were also dozens of unforgettable Instagrams posted in the designer's honor. Check out the top Instagrams below and peep grainy footage of Kanye's performance via Justin Beiber's IG. Happy birthday, Riccardo!
