Hold on to your seats, little monsters. On Sunday night, Lady Gaga performed the Super Bowl 51 halftime show in Houston, and we haven't been the same since. The singer was on top of the world (or at least the arena) as she kicked off her big performance. Aside from suspending herself above the stage, she blew everyone away with a collection of her greatest hits, including "Bad Romance" and "Million Reasons." Relive every iconic moment ahead.
