This past weekend Alicia Keys was in attendance for the Givenchy show during Paris Fashion Week, joining fellow allstar celebs such as Kanye West, Diddy & Cassie. The New York native was sure to hit up the festive after-party as well, and she gave the crowd a bit of a treat as she serenaded Givenchy creative director, Riccardo Tisci, with an impromptu performance of “Empire State of Mind.” Check out the camera phone footage below of her quick performance.
