The Jonas Brothers have been digging deep through their contacts lately, and those texts are paying off. (No word if they’re sent via T9 on a flip phone, but it would be appropriate.)
The brothers embarked on their JONAS20: Greetings from Your Hometown Tour on Aug. 10, and it’s been one surprise after another ever since as the boys have been inviting renowned guests to surprise fans at different shows. The list has included fellow boy bands Plain White T’s, Hanson, All Time Low and more, but they truly struck the nostalgic cord with millennial favorites such as Demi Lovato, Fifth Harmony, Jesse McCartney and Jojo.
Below, check out some of the guests who have taken the stage with the JoBros.
Demi Lovato

Millennial Disney fans lost their minds when videos of the brothers with Demi Lovato started making the rounds the night she joined them at MetLife Stadium on Aug. 10. Lovato, who starred with the brothers in the Camp Rock movies (and also dated Joe back in the day) sang “Gotta Find You,” “This Is Me” and “Wouldn’t Change a Thing,” with the band.
Papa Jonas (and Other Family Members)
The same night, the boys also sang “When You Look Me in the Eyes,” with their dad sitting at the piano. The moment was extra special as other family members were also spotted on stage. Kevin’s wife, Danielle and their daughters Alena and Valentina could be seen on stage, as well as youngest Jonas brother Frankie.
Dean Lewis, with whom the boys collaborated on the song “Loved You Better,” also hit the stage to sing the ballad and so did their former bodyguard, Big Rob.
Jesse McCartney — Twice!

Jesse McCartney also graced the stage at MetLife, singing his 2004 hit “Beautiful Soul” with the band.
McCartney joined the JoBros again in Boston on Aug. 23 (again, to ear-splitting screams).

The JoBros thrilled the crowd at the Credit Union 1 Amphitheatre in Tinley Park, Illinois, with their hometown band The Plain White T’s. Of course, one of the songs on the set list of the Aug. 26 show was “Hey There Delilah.”
Russell Dickerson
Not only was it a party on stage with Russell Dickerson at Little Caesars Arena in Detroit on Aug. 28, but the Jonas Brothers also roped the singer into their backstage shenanigans as seen in the video above.
Fifth Harmony
Only a band as mighty as the Jonas Brothers would be able to reunite Fifth Harmony. The girl band (sans Camila Cabello) performed together for the first time since 2018 at the Dos Equis Pavilion in Dallas on Aug. 31.
Kelsea Ballerini

For the Aug. 31 stop in Dallas, the band wowed fans with an appearance by Kelsea Ballerini. “definitely don’t tell 13 year old me i was barefoot bee bopping on stage singing fly with me with the @Jonas Brothers,” Ballerini captioned a post recapping the night.
Ryan Cabrera, another millennial favorite, also performed with the band that same night.

It was a perfect medley of guitars and silky vocals as the Jonas Brothers and Jason Mraz performed “I’m Yours” at the Sept. 4 show in Chula Vista, California.
5 Seconds of Summer

For their L.A. show on Sept. 6, the brothers created a mega-band with fellow musicians 5 Seconds of Summer.
“We’ve known them for a couple years now. We’ve had a lot of mutual collaborators as well,” Joe said in his intro.
He continued, “But deep down, these are just great people. And we love seeing great people win when they’re out there doing their thing. Even if they’re from a different country… our friends, your friends, make some noise for our boys 5 Seconds of Summer.”
The boys also shared the stage with John Legend the same night.
