Dan + Shay and Kelsea Ballerini made surprise appearances during Tuesday (September 10th) night's Jonas Brothers concert in Nashville. Dan + Shay joined Nick, Kevin and Joe Jonas in a rendition of the duo's hit "Tequila," while Kelsea took the stage to join show opener Bebe Rexha on "Meant to Be."

Kelsea also finally got to meet her longtime faves the Jonas Brothers. She posted an old video of herself as a teenager talking about why she should get to meet the trio on Instagram along with a new photo of herself with the brothers Tuesday night. She wrote, "Only took 12 years to win the JoBro meet & greet. swipe for my 2008 contest entry from DEEP IN THE ARCHIVES . . ."

You may recall that Dan + Shay sang their hit "Speechless" during Joe Jonas' Las Vegas wedding to Sophie Turner after the 2019 Billboard Music Awards.
