Riccardo Tisci, the beloved creative director of Givenchy and certifiable party animal, turns 40 on August 8. To celebrate the milestone, he threw one hell of a bash in Ibiza Friday night, complete with a surprise performance by Kanye West, a "Happy Birthday" serenade from Kate Moss and Naomi Campbell, and some really strange moments between Justin Bieber (who has already gotten himself into a bit of trouble in Ibiza) and the Kardashian/Jenner family.
The party was sponsored by Beats by Dre. (Tisci was gifted a pair of 24-carat gold headphones in honor of his big day) and the dress code was "black subversive glamour," which some of the guests — which included the likes of the Brant brothers, Zac Efron, Jared Leto, Natasha Poly and many more — took very seriously.
See below for some of the best snaps of Tisci's big weekend. Bonne anniversaire!
