Singer Brandi Carlile is opening up about why she - as an openly gay artist - decided to sing "America the Beautiful" at Super Bowl LX despite the country's turbulent and divisive political times. "I have my own moral code, my own moral imperative, that I have to answer to at the end of the day, as a wife and a mother, and I believe in my ability and responsibility to do this, and that's why I'm here," Carlile, 44, told Variety in an interview published on Saturday, February 7.
