That's why it was the best performance of the night, followed by Christina and Shakira. Vocally Christina had the best performance, but physically Beyonce had the best one then Shakira. That was very talented, I was in aw at that dance break scene. I couldn't believe what I saw. It's crazy how they did that. It must have took many many many trials to get it down, and see, who cares if it's choreographed, that still means they have to do.
I can only imagine how much time it took to get all of the dancers to time their moves along with the "clicks" of the track... Best performance choreography-wise.
