Christina Aguilera to sing nat'l anthem
NEW YORK -- Christina Aguilera will sing the national anthem at the Super Bowl in Texas on Feb. 6.
The five-time Grammy award-winning singer will be making an encore at the NFL championship. She was part of the halftime show during the 2000 Super Bowl.
The NFL and Fox made the announcement Monday.
Other stars to have sung the national anthem at the Super Bowl include Carrie Underwood, Billy Joel, Diana Ross, Neil Diamond, Mariah Carey and Beyonce Knowles.
The previously announced halftime show will feature The Black Eyed Peas.
The NFL announced Monday that the retractable roof at the $1.3 billion stadium would be closed for the game.
NFL spokesman Brian McCarthy said Monday the decision was made well in advance of the Feb. 6 game so the league could have a "singular focus" on logistics.
The weather in Dallas-Fort Worth could be good enough for an open-air game, but there's also a risk of freezing temperatures.
The Cowboys opened the roof when they had 105,121 for the first regular season game at their new stadium in 2009. Attendance could surpass 100,000 for the Super Bowl, but only about 93,000 will be inside the stadium.
