Madonna posted “It's official, we are here,” on her Facebook page Wednesday, along with a photograph of Lucas Oil Stadium.
A press conference regarding the halftime show was held Thursday in the White River Ballroom, where Madonna spoke about the upcoming performance.
The pop icon said she is nervous about having to perform.
"I have to keep pinching myself. I can't believe I'm here," said Madonna.
She's been training since December, pulling a hamstring and getting physical therapy.
"Lots of warm ups and tapos and ultrasounds. I feel like I am one of the football players," said Madonna.
Madonna said her focus on the hush, hus performance. She's teamed up with Cirque Du Soliel and Jamie King. She said she will sing three old songs and one new. What those songs will be is still unknown, though.
"I really don't want to blow the surprises. I want people to be knocked out of their seats from beginning to end," said Madonna."The envelope I am pushing is just for a special show, which will, I think, entertain all age groups and will be a feast for the eyes and the ears."
A 2008 Rock and Roll Hall of Fame inductee, Madonna is ranked by the Guinness Book of World Records as the top-selling female recording artist of all time.
She follows other high-profile acts who have been selected to perform at the Super Bowl in recent years, including the Black Eyed Peas and Usher, during the most recent championship game at Cowboys Stadium in Texas. Other past performers include Bruce Springsteen, Prince, The Rolling Stones and Paul McCartney.
The league calls the show "the most-watched musical event of the year," with more than 162 million people tuning in last year in the United States alone.
Madonna released a teaser to her Super Bowl performance on her Facebook page Thursday.
