Taylor Swift went back to her country roots on Wednesday night, bringing out Miranda Lambert as her surprise guest on the 1989 World Tour stop in Greensboro, North Carolina.
"Make some noise, guys, ‘cause Miranda Lambert is here!" Swift announced to the crowd, who promptly lost their minds.

The pair brought the house down with a rendition of Lambert’s sassy hit "Little Red Wagon."
Swift, who has also welcomed country stars like Sam Hunt, Dierks Bentley, and The Band Perry throughout her 1989 World Tour, took to social media after the show to share clips and pics of the two performing together.
