WATCH: Lady Gaga delivers sparkling All-American Super Bowl half time show
Lady Gaga performed a medley of her biggest hits during a patriotic performance at the Super Bowl, but avoided using the platform to voice her opposition to Donald Trump.
The music star, who has been vocal opponent of the US president, repeated the words of America's pledge of allegiance during her energetic set at the NRG stadium in Houston, Texas.
But the singer, who staged a protest outside New York's Trump Tower after the US election result, did not mention the president on stage, telling the crowd: "America, world ... we're here to make you feel good."
Gaga, 30, started the half-time show by standing on the stadium roof where she sang God Bless America and This Land Is Your Land.
She then spoke the words: "One nation under God, indivisible, with liberty and justice for all."
Dressed in a metallic leotard emblazoned with sequins and wearing knee length boots, Gaga was lowered into the stadium from the roof by a wire.
She performed Poker Face, Born This Way and Telephone before donning a gold jacket with spiked shoulders for her rendition of Just Dance.
As she played piano for her song Million Reasons, Gaga said; 'Hey dad, hi mum', before completing her set with a performance of Bad Romance surrounded by dozens of dancers.
Gaga ended the half-time show by jumping off the stage to catch a football thrown towards her.
Super Bowl 51 saw the New England Patriots, led by star quarterback Tom Brady, take on the Atlanta Falcons in American football's showcase event.
Celebrities in the crowd included Sir Elton John, John Travolta, Mark Wahlberg, Usher, John Legend and his wife Chrissy Teigen and Brady's wife, model Gisele Bundchen.
Former President George Bush and his wife Barbara Bush took part in the coin toss before the match, in their first public appearance since the couple were admitted to hospital last month.
Three stars from the hit Broadway musical Hamilton updated the lyrics of America The Beautiful during their performance before the match.
Phillipa Soo, Renee Elise Goldsberry and Jasmine Cephas Jones, added the words "sisterhood" after singing the lyrics "brotherhood".
Vice President Mike Pence attended the game, while country singer Luke Ryan took to the field to sing America's national anthem.
Pop star Taylor Swift performed at a pre-Super Bowl party in Houston the night before the match.
