The country music star, 39, surprised the audience at the popular country music festival when she brought the Canadian singer up on stage at Nashville’s Nissan Stadium to sing two songs with her on Friday evening. In a video from the moment posted up on social media, Lambert, who wore a long-sleeved black shirt and a skirt with bright pink fringe, could be seen walking across the stage to a drum beat while making the introduction. “I’m out here to make more badass moments happen right now. Will y’all welcome my new bestie, Ms. Avril Lavigne to the stage?” she asked the audience.

The pair then began their rendition of Lambert country rock single “Kerosene,” singing a chorus line and verse, before the song transformed into the pop strings of Lavigne’s “Sk8er Boi.” The crowd cheered at the transition before Lavigne started singing along to her hit single. Lambert joined in on singing the chorus, and the pair rocked along while jumping up and down to the beat. Miranda Lambert and Elle King.
