Kelsea Ballerini helped kick off the week of the 2016 CMA Music Festival at the Nash Country Kick-Off Party on Tuesday (June 7), and she did not disappoint: She brought Hunter Hayes onstage as a surprise guest, and the two performed one of Hayes' biggest hits.

Ballerini and Hayes sang the Grammy-nominated, multi-platinum, No. 1 hit "Wanted," much to the delight of the crowd. The audience sang along with zeal as Ballerini and Hayes took turns singing different parts of the tune, as readers can see in the above video.

But Hayes wasn't Ballerini's only surprise guest. The rising star also welcomed Hillary Scott from Lady Antebellum onstage. After the show, Ballerini posted a photo of the two singing together, saying, "When @hillaryscottla helps you kick off CMA Fest, it's kicked off correctly."

Jon Pardi and Levi Hummon also performed at the Nash Country Kick-Off Party, which took place at Nashville's Cannery Ballroom. The 2016 CMA Music Festival officially begins on Thursday (June 9), and a massive amount of country stars are slated to perform throughout the four-day event in Music City. For all the information on the festival, visit the CMA Music Festival’s official website.
