``I have been performing the anthem since I was 7 years old, and I must say the Super Bowl is a dream come true,'Aguilera said.Country star Martina McBride did the honors in Pittsburgh on Sunday, where the Steelers beat the New York Jets, while fan favorite Jim Cornelison sang before the contest between the Packers and Bears in Chicago - bumping ``American Idol' winner Lee DeWyze. Cornelison regularly sings ``The Star Spangled Banner' before Chicago Blackhawks games.
The gig comes in the wake of Aguilera's star treatment on Hollywood's Walk of Fame in November, not to mention the five-time Grammy winner's acting debut in ``Burlesque.'
The Packers and Steelers will meet Feb. 6 at Cowboys Stadium in Arlington, Texas, with the Black-Eyed Peas headlining the halftime show. More than 153 million people watched last year's Super Bowl.
