Zach Bryan brought a surprise guest onstage during his show in St. Louis the other night, but this one was a little out of left field.
During "Revival", rapper Sexyy Red came out onstage to pop some booty. St. Louis IS her hometown, though, so it wasn't TOO unbelievable.
Zach's guests at previous shows have included Bruce Springsteen and Kacey Musgraves. They did not twerk.
