Florida Georgia Line reconnected with the Chainsmokers live in Cincinnati for a surprise performance of "Last Day Alive" on the EDM duo's Memories: Do Not Open Tour.

A tweet teased Wednesday's (April 26) collaboration.

The original closes the Chainsmokers' debut album. FGL presented them with the iHeartRadio Music Award for best new artist during the 2017 telecast in March.

FGL are on tour through the fall. The Smooth Tour 2017 with Nelly and Chris Lane launches June 2 in Austin, Texas. Ryan Hurd joins the tour on June 15 in Wantagh, New York.
