WATCH ZACH BRYAN BRING THE ‘HAWK TUAH' GIRL ONSTAGE AT NASHVILLE CONCERT

From Springsteen to "Spit on that thing": Zach Bryan's Quittin Time Tour has featured plenty of diverse onstage guest appearances, from rock gods to country stars to NFL quarterbacks to, now, internet celebrities, as the viral "Hawk Tuah" girl popped up at his concert Saturday.

Performing at Nashville's Nissan Stadium, Bryan once again used the encore "Revival" to bring out onstage whatever celebrities might be the building to assist on backing vocals, and on Saturday that meant Hailey Welch, the woman behind the viral internet video that everyone is talking about: 

Making her first public appearance since going viral, Welch even added an exuberant "HAWK TUAH!" to the proceedings:

While Welch might get all the headlines out of Saturday's show, she wasn't even the biggest guest to grace the Nissan Stadium stage, as Kacey Musgraves also showed up mid-set to perform her and Bryan's "I Remember Everything":

As the person now thrust into the role of Welch's brand manager following the "Hawk Tuah" video told Rolling Stone this week, "Of course she hasn't gotten a dime from the first viral video that went out. Nobody was asking permission for her to do nothing, neither. I just wanted her to get some profit off of this deal." 

Welch has already sold over $65,000 of "Hawk Tuah" merch as of earlier this week, and while she isn't profiting off the video itself, its infamy has led to some other cool opportunities, including being Bryan's one-night-only backup singer.
