Zach Bryan's Quittin Time Tour has been full of surprise onstage appearances, ranging from rock legends to internet sensations. During his recent performance at Nashville's Nissan Stadium, Bryan brought out internet celebrity Hailey Welch, known for the viral "Hawk Tuah" video. Welch made her first public appearance since going viral, adding her signature catchphrase to the performance. However, she was not the only star to join Bryan on stage that night, as Kacey Musgraves also made a guest appearance to perform with him. Despite the viral success of the "Hawk Tuah" video, Welch has not received any profits from it. However, she has capitalized on the fame by selling over $65,000 worth of merchandise. This unexpected collaboration showcases the power of social media and the opportunities it can bring to ordinary individuals.
