Lady Antebellum will sing on NBC's Today on Wednesday (Dec. 24) to celebrate Christmas Eve. The trio will perform "Baby, It's Cold Outside" (available now as an iTunes exclusive) and their debut single, "Love Don't Live Here." Lady Antebellum is nominated for a Grammy as best new artist. "I'll definitely be doing some last-minute Christmas power shopping in the city," said Lady Antebellum's Hillary Scott. "I can't think of a better way to end what has been a truly unbelievable year for us."
