Once again, the Super Bowl halftime show is the biggest musical performance of the year. Award-winning singer Usher just took the stage, with a slightly longer halftime performance than usual, getting two extra minutes, up from 13 to 15 minutes.

Usher came out wearing all white and began his performance with "Caught Up," kicking things off with a bang. He was joined by dancers on the field, looking like an authentic Las Vegas performance. He was also joined by a marching band that had a significant presence during "Love In This Club."

He brought out singer Alicia Keys, who before the event was reported to be the surprise guest. Keys was revealed with an all red piano, with an outfit to match. She began singing her own song, "If I Ain't Got You," joined by Usher. They then transitioned to "My Boo," a song they did together in 2004.

Jermaine Durpri was another surprise guest, one that was not reported ahead of the game. H.E.R. later came out with her signature guitar, showing off to the Super Bowl crowd.

As H.E.R. was performing, Usher put on roller skates and performed in skates while performing "OMG" with will.i.am. The surprise guests did not end there, Lil Jon and Ludacris joined Usher to their perform their hit song "Yeah!"

During their performance of "Yeah!" the marching band spelled out "USHER."
