Carrie Underwood let her hair down last night  while cheering on her husband Mike Fisher at the Nashville Predators' hockey game against the Tampa Bay Lightning. Carrie was spotted enjoying the game from a private suite at Nashville's Bridgestone Arena where she noshed on nibbles and chatted with a few girlfriends and suite mates the Swon Brothers. She even joined the crowd in chanting, "It's your fault," at the opposing team's goalie when the Predators scored a goal. The Predators defeated the Lightning, two-to-one. Next week, Carrie moves to New York to begin training for the Sound of Music, airing live December 5th on NBC
