Bebe Rexha had a surprise in store for her Nashville fans when she performed at the Bridgestone Arena in Music City on Tuesday night (Sept. 10). The pop star invited country singer Kelsea Ballerini to the stage for a surprise duet on "Meant to Be," which she originally recorded with Florida Georgia Line.

Click on the fan-shot video above to watch the performance, which took place part way through Rexha's set opening for the Jonas Brothers on their current 2019-2020 Happiness Begins Tour. Rexha sings the first verse and chorus solo, while Ballerini joins in to perform the second verse. The women trade off on the rest of the verses and bring their voices together for the chorus in a dual performance that's very different from the treatment Rexha and FGL's Tyler Hubbard and Brian Kelley gave their radio hit from 2017.

Tuesday night's set also included a surprise duet between headliners the Jonas Brothers and Dan + Shay, who joined the pop superstars for a collaboration on Dan + Shay's own hit, "Tequila."

Ballerini has been in the spotlight quite a bit recently. She recently revealed that she has completed the tracks for her much-anticipated third solo album, and she released the album's first single, "Homecoming Queen?" on Friday (Sept. 6). The starkly emotional track shows the pop-country singer-songwriter at her most vulnerable, and in the video for the song, she literally strips away the artifice to appear without makeup as she delivers a powerful lyric about feeling like you can't show your true self.

Ballerini has not yet announced the details for her third studio album.
