Jay-Z smiled as he made his way through some adoring fans on his way out of Maddox Club in London last night. Whether or not his kick-ass Glastonbury performance helped him gain popularity, it looks like the NY born and bred rapper has more than a few loyal followers overseas. He seemed to have a blast inside partying with Pharrell, which all must have only been made that much sweeter by the news that "99 Problems" is back on the UK charts after his show over the weekend.
