"We're not allowed to give away the set list, but it will be packed with energy -- what the Black Eyed Peas bring," band member Fergie said at a news conference Thursday.
"We want everybody to have a good time and just dance, party," will.i.am said about the performance that's expected to include R&B star Usher and former Guns 'N Roses guitarist Slash.
A person familiar with the plans for Sunday's halftime show told The Associated Press that both musicians were scheduled to make surprise appearances. The person spoke to The AP on condition of anonymity Wednesday because the musicians' performances wouldn't be announced.
"Hopefully we will bring the heat because it's cold as hell here in Dallas," Black Eyed Peas band member Taboo said.
The band spoke at a news conference in downtown Dallas on the third consecutive day of subfreezing temperatures during a rare cold spell that greeted the first Super Bowl week in North Texas.
Taboo said the opportunity to provide entertainment for the NFL's ultimate game is "a dream come true for us as football lovers."
Fergie, who is a minority owner of the Miami Dolphins, said it was a "huge honor" to be picked as halftime performer.
"Sunday football is a serious day in our homes," Fergie said. "Super Bowl Sunday is the day that I can go all out -- cheat -- eat the seven-layer dip, all the Italian food and scream at everybody."
The six-time Grammy award-winning Black Eyed Peas have sold more than 28 million albums worldwide and are known for songs such as "Boom Boom Pow," "I Gotta Feeling" and "Imma Be."
"Some people write songs for radio. Some people write songs for clubs. We like to write songs for life," will.i.am said, adding that he is proud that many of their energetic songs are featured at sporting events.
The band also will bring some technology to the show as will.i.am will tweet during the performance.
Keith Urban and Maroon 5 will perform during the pregame festivities Sunday. Christina Aguilera is set to sing the national anthem, and Lea Michele of "Glee" will sing "America the Beautiful."
