Kelsea Ballerini and Halsey joined forces for an impromptu karaoke performance at a bar in Nashville.

Those who were lucky enough to be in Santa’s Pub last night, July 18, got a free concert! Halsey was in town for a show at Nashville’s Ascend Amphitheater, which Ballerini attended, reports The Boot.

Halsey tweeted: “Well me and ended up doing a karaoke rendition of “Picture” by Kid Rock in a dive bar where no one knew our names, so how was your night?”
