Givenchy’s Riccardo Tisci has been chillin' in L.A. this week, and absent from his side are BFFs 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 get invited?). But it seems Tisci's found a new bud: the shy, mysterious Robert Pattinson. R-Pattz looked totally at home with the fashion crowd at a party for Tisci and photog 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, R-Pattz and Yeezy in matching Bambi hoodies?! We can only hope...
