In reply to Benron.

She wasn't lip-syncing, she had the back track on singing over it. Beyonce never lip-syncs. If she doesn't sing, then she doesn't hold a mic, she would just dance. I've been to all her concerts, I know the difference.

Beyonce learned from her 2003 performance at EMA awards LOL, when her backtrack was skipping. Good thing she was singing LIVE.
