Beyonce wasn't messing around with her halftime performance.

No immediately obvious malfunctions, no weird cross-genre collaborations with rock stars or one-hit wonders.

Just Beyonce, then Kelly Rowland and Michelle Williams to bring back Destiny's Child.

Beyonce sang a medley of hits, including "Crazy In Love," ''Baby Boy" and "Single Ladies." She also danced in front of a screen using multiple images of herself as a backup dancer when she wasn't backed by her all-female band and nearly two dozen dancers.

But when Rowland and Williams sprang up from trap doors onstage, the world got the performance it was anticipating.

Not surprisingly, the show dominated worldwide Twitter trends as the second half began.
