Carrie Underwood may be gearing up for the biggest performance of her life. Sports blog TerezOwens.com reports that Underwood is in talks to headline the 2015 Super Bowl halftime show. As the site reports, Underwood already has string ties with the league. In addition to taking over for Faith Hill in performing the theme song for NBC’s Sunday Night Football last year, Underwood performed the national anthem at Super Bowl XLIV in 2010, and performed with Aerosmith lead singer Steven Tyler at Super Bowl XLVI’s Pepsi Super Bowl Fan Jam. It was also recently announced that the “Blown Away” singer will take part in the 2015 Super Bowl pre-game kickoff video.
