Fifth Harmony reunited on stage for the first time in seven years during the Jonas Brothers concert on Sunday night. The Work From Home singers sparked reunion buzz on Sunday morning when they issued their first social media post in seven years, writing "#FifthHarmonyFollowSpree," on the band's X account. Fans didn't have to wait long to find out when their comeback would launch, as Ally Brooke, Normani, Dinah Jane and Lauren Jauregui hit the stage together for the first time since their 2018 hiatus only several hours later. The crowd in Dallas, Texas went wild as the foursome made a surprise appearance and performed their two biggest hits - Worth It and Work From Home - in the middle of the Jonas Brothers' show. The foursome were not joined by their bandmate Camila Cabello, who quit the group in 2016. They shared a clip of the performance on X and Instagram with the caption, "Where were you on August 31, 2025? Thank you @jonasbrothers for having us. Felt amazing to be back." To celebrate the reunion, the band released new merchandise on their web store, a black T-shirt and hoodie featuring the group's name and the slogan, "Where were you on August 31, 2025?" The four-piece also opened a community on the fan platform WeVerse. According to Variety, they recorded a video message promising fans that they'll be chatting to them "soon". Earlier this year, it was reported that Fifth Harmony were in talks to reunite in 2026 to mark the 10-year anniversary of their second studio album, 7/27, and Work From Home. Insiders told The Hollywood Reporter that the quartet were planning to go on tour and film a documentary about their comeback. The band was formed on The X Factor U.S. in 2012.
