She then swung down from the roof to a stage suspended on cables and embarked on a meticulously choreographed 13-minute set of her greatest hits during the National Football League championship game between the New England Patriots and the Atlanta Falcons.
Ahead of her high-profile performance, watched by more than 100 million US viewers, Gaga, 30, said in a post on the Instagram social media network that she planned to headline the slot entirely on her own, eschewing a tradition of halftime main acts bringing on special guests.
Dressed in a silver, sequined bodysuit and matching heeled boots, Gaga sang her dance hits Poker Face and Born This Way - an anthem for self-confidence and inclusion - as she performed aerial acrobatics while suspended in the air.
