Beyoncé – Best Thing I Never Had (Live on Jimmy Fallon)

In support of her chart-topping LP 4, Beyoncé visited Late Night with Jimmy Fallon last night and conquered the musical stage with The Roots during her performance of her latest single "Best Thing I Never Had." The staff of the TV show seemed to be blown away by the gig as they posted the taping online before it was televised. Watch Bey's performance above.
