Beyonce vs. Alicia Keys

Last night at Madison Square Garden Alicia Keys took the stage as part of her tour. It looked like a great show and then *gasp* it got even greater as the Knowles joined her on stage. Jay-Z was there to do "Empire State of Mind" while Beyonce took to the stage to perform "Put It In A Love Song". The two ladies seemed to go at the song pretty hard, so that leave the question: who ran it??
