Givenchy’s Riccardo Tisci has been cruising around L.A. this week, and absent from his side are best mates Kanye West and Kim Kardashian. Sure, they've got lots to do—she's doting on North, he's performing at Leo DiCaprio's b-day bash (oh, you didn't crack an invite?). But it seems Tisci's found a new bud: the shy, mysterious Robert Pattinson. R-Patz looked totally at home with the fashion crowd at a party for Tisci and photographer Marcus Piggott (below). Tisci Instagrammed the pics, which show Rob and his beanie playing the piano—simply captioned ‘R.’ Um, they're already on a one initial basis? What's next, Rob and Yeezy in matching Bambi hoodies?! We can only hope...
