VIDEO : Miranda Lambert Joined Taylor Swift on Stage for a Duet

At this point, I?m not sure how Taylor Swift has anyone left to act as a surprise performer, but she?s done it again! Miranda Lambert joined Taylor on stage for a rowdy performance of ?Little Red Wagon.? There was a lot of backyard swagger on stage, for sure. The duo performed in Greensboro, North Carolina as a part of Taylor?s 1989 World Tour. Before taking the stage, Taylor called Miranda ?one of my favorite artists.? We couldn?t agree more.
