The group later shared a video of their performance on Instagram, writing, “Where were you on August 31, 2025? Thank you @jonasbrothers for having us. Felt amazing to be back.” Ally Brooke commented on the post, calling it “special,” while former memberCamila Cabello showed her support by sharing four red heart emojis. The Jonas Brothers also celebrated the moment, posting a clip of the performance and expressing, “An honor to have our friends @fifthharmonyup on stage tonight in Dallas on the Greetings From Your Hometown Tour.”

Rumors of a reunion had been circulating for months, fueled by various hints from the members. As early as November 2023, Ally Brooke discussed the possibility in a Billboard interview, stating, “We’re women now and we have grown so much and we have done our own thing, gone our own ways and gone our own path. And now we’re together in a different light. I’m trying to reunite with them, so I think some sort of reunion may happen.” Brooke and Dinah Jane further teased fans in March 2024 at the Billboard Women in Music event.

When asked about getting the group back together, Brooke responded, “We’ll see… we’re not sure,” with Jane adding, “I love that our fans can reminisce on such good times and I love that we’re getting the credit again. Our music was very impactful at the time and I feel like it was kind of overlooked, to be honest. So now that it’s reviving again on its own it just shows our music speaks for itself.”
