It's a warm summer night. You’ve managed to score a coveted ticket to the Jonas Brothers concert, where you’re singing at the top of your lungs about scorching temperatures, outselling Kelly Clarkson and getting bitten by the love bug. Maybe you’ve bought some JoBros merch too. A tote bag. A “JB” dad hat. A graphic tee with the bros smoldering at the camera.

The fangirl in you has been unleashed in a way that only a trio of brothers from New Jersey could unleash it. It feels like 2008 all over again, only it's not. It's August 2025.

Nick, Joe and Kevin Jonas of the Jonas Brothers kicked off their JONAS20: Greetings From Your Hometown tour on Aug. 10. In just six shows, they’ve already served up what can only be described as a millennial dream come true. In addition to performing their earlier hits, the brothers have already invited a handful of bands and artists who were popular in the aughts to join them onstage as surprise guests at each tour stop. Aughts-era pop-rock bands Boys Like Girls and the All-American Rejects were also tapped as opening acts for select dates.

Demi Lovato, perhaps the most notable guest so far, was greeted by ear-shattering shrieks from millennial fans when she strutted onto the MetLife Stadium stage on the opening night of the tour. Lovato performed two Camp Rock-era duets, “This Is Me” and “I Wouldn’t Change a Thing” with Joe, whom she dated in 2010.

For Lovato, who struggled with sobriety and her mental health at the height of her Disney stardom, taking the stage with the brothers was a “healing” experience.

“It was so healing for me too,” she said on the Chicks in the Office podcast last week. “You know, we’ve been through so much together, all of us, the Jonas Brothers and I.”

The “Fast” pop star wasn’t the only nostalgia-inducing guest that night — Jesse McCartney serenaded millennials with his Disney hit “Beautiful Soul,” and Switchfoot performed their 2003 song “Meant to Live,” along with the JoBro track “Hold On.” The whole Jonas family — mom Denise Jonas, dad Kevin Jonas Sr., brother Franklin Jonas, Kevin’s wife, Danielle, and their daughters, Valentina and Alena — also took the stage to sing “When You Look Me in the Eyes” to emotionally close out the first show of the tour.

Two days later, on Aug. 12, the boys descended upon Bristow, Va., where they brought out pop-punk phenoms All Time Low to perform their 2007 single “Dear Maria, Count Me In.” For their Camden, N.J., show on Aug. 14, the Jonas Brothers tapped the Click Five, the band they actually opened for 20 years ago, to rock out to their 2005 hit “Just the Girl” onstage. Hanson, a fellow iconic trio of singing brothers, played a rendition of their song “MMMBop” with Nick, Joe and Kevin during their Virginia Beach tour stop on Aug. 15.

Sunday night’s show in Hershey, Pa., was filled with more aughts-era greatness. Pulling on the heartstrings of millennial Warped Tour attendees everywhere, the brothers brought out Cartel to perform their 2005 single “Say Anything (Else).” Rounding out the guest appearances for the Aug. 17 show was none other than Hoobastank, who performed their 2003 ballad “The Reason.”

On Monday night in Bethel, N.Y., Boys Like Girls made their debut as a Greetings From Your Hometown tour opener. The pop-punk band played several tracks from their 2006 and 2009 albums, including “The Great Escape,” “Hero/Heroine” and “Two Is Better Than One.”

Troves of millennial fans have flocked to social media to gush about all the nostalgic appearances so far.

One fan commented on a TikTok video, “It’s like Joe is going through my old iPod,” while another wrote, “I fear a big portion of the crowds are going to be too young to appreciate these guests. So good for us 30-something’s lol.” Added one more fan, “Switchfoot and now Cartel??? I didn’t recognize your game Jonas Bros.”

The Greetings From Your Hometown tour hits different for those of us who grew up with the Jonas Brothers. It’s a celebration of our childhood — of the music that dominated our iTunes libraries and soundtracked our adolescence. Millennials, it seems, are in agreement: There’s comfort in knowing that these bands and artists are still here and still down to rock out with us after all this time.
