Riccardo Tisci, Creative Director of Givenchy, turns 40 today. The designer kicked off his birthday celebrations last week in Ibiza with a star-studded party. Guests included Naomi Campbell, Jared Leto, Kate Moss, Kim Kardashian, Kanye West, and, rather surprisingly, Justin Bieber…who allegedly managed to get Orlando Bloom barred from the event. The gifts have already started rolling in, from Beats by Dre's 24 carat gold headphones, to a salacious 'Gram from Kim Kardashian, to a performance by Kanye West that Tisci called "the best present of my life."
