Beyonce Rehearses “1 + 1″ Backstage At ‘American Idol’

Beyonce killed it not once but twice on American Idol last night, and if you had any doubts that Bey’s vocal theatrics are somehow manufactured in a studio or aided by fancy theatrics, Jay-Z quells all doubts. Hova secretly taped his missus rehearsing her new ballad “1 +1″ backstage at the Nokia Theater before performing during the Idol finale, and it’s a dress rehearsal worth watching.
