During a recent concert in Pennsylvania, Luke Bryan treated his audience to an impromptu dance performance that took an unexpected turn. As his band played Bruno Mars’ “Uptown Funk,” Bryan enthusiastically showcased his hip-swiveling moves. The band then transitioned into Michael Jackson’s “Billie Jean,” and Bryan attempted a moonwalk, much to the delight of the crowd. However, the intense dance routine appeared to take a toll on the singer. Pausing to catch his breath, Bryan acknowledged the viral potential of the moment, stating, “Sh-t, I’m tired. I’m sure all of that will go viral in the morning.” He then revealed to the audience that he believed he had “pulled [his] left nut sack” during the performance. Bryan is currently continuing his “Country Song Came On” tour, which is scheduled to run through October. (American Songwriter)
