The Jonas Brothers announced their massive summer "Remember This" tour on Wednesday (May 19), which is slated to kick off on Aug. 20 at the Park Theater in Las Vegas. The follow-up to the siblings' 2019 "Happiness Begins" reunion tour will feature country singer Kelsea Ballerini as their opening act.

"We couldn’t be more excited to officially announce we are going on tour THIS summer and bringing our friend Kelsea Ballerini!" Joe, Nick and Kevin said in a statement announcing the outing. "If this past year has taught us anything, it’s that we need to remember the important moments in our lives. We hope these shows will be special moments for our fans, our friends and our families and we can’t wait to see all their faces soon!!"

The 44-date Live Nation-promoted tour will feature stops in San Francisco, Chicago, New York, and Houston before winding down on Oct. 27 with a show at L.A.'s Hollywood Bowl. Before hitting the road, the brothers will team up with NBCUniversal for a Tokyo Olympics activation built around  their upcoming single “Remember This.” The song will debut on the opening night of the U.S. Track & Field Trials on June 18, between 10 and 11 p.m. ET on NBC, one month before the Olympics are scheduled to kick off on July 23.
