The Jonas Brothers started their tour for 20 years of anniversary at the Metlife Stadium on Sunday in their home country New Jersey. The band took over the top trends on social media, all thanks to their reunion with their special guest, Demi Lovato. The reunification took place on Sunday, whereby the singers met on the stage for an epic performance. This marked their first stage appearance since the leading role in the Disney Channel Hit 'Camp Rock' 2008, where Joe Jonas and Lovato played love interests on the screen (and allegedly outside the screen).

The moment became viral almost immediately and put the concert quantity and the online fandom in frenzy.Lovato later divided photos from The Night on Instagram and wrote: “Hey Siri, play that I from Mitchie Torres.” The official side of the Jonas Brothers also posted pictures from reunification, but it was Nick Jonas' Post who marked the most emotional reactions.Nick invited several photos, including one of him who hugged Lovato, and wrote: “I can't put into words what it meant for me and my family last night. To grow up from this iconic event location and have the chance to play a sold out of 52,000 people was really a dream.”While he did not directly tell Lovato, he added: “Not to mention the special guests who were gracious enough to provide incredible achievements that mean the journey on which we have been in the past 20 years. My heart is full.”He concluded: “It will probably take a few days, maybe weeks to completely unpack what happened on August 10, 2025, but I will certainly tell you one thing – I can't wait to come back on stage tomorrow evening and continue this celebration of life, family and music.”Viral emotional momentAfter her duet, Joe was rumored to his former co-star and how he had the ex-girlfriend. Then Lovato hugged Nick and patted him on his back before greeting Kevin with another hug.The fans were surprised to see the advertisement of affection, given the history of Lovato with the brothers – including romantic links to Nick and Joe. “It's so cute, but I am shocked that Demi agreed to be in the same environment as Nick,” wrote a fan online.Social Media BuzzBefore Nick's Post, Lovato found that Lovato had recently followed her former best friend and had rumored ex, Nick on Instagram.
