Lady Antebellum is performing on NBC's "Today" show tomorrow to celebrate Christmas Eve. The trio will sing "Baby, It's Cold Outside" (now available exclusively on iTunes) and their debut single, "Love Don't Live Here." The Grammy-nominated band has had quite the year. As Hillary Scott said, "I'll definitely be doing some last-minute Christmas power shopping in the city. I can't think of a better way to end what has been a truly unbelievable year for us."
