Jonas Brothers Surprise Fans by Bringing Out Demi Lovato at MetLife Stadium Concert

Fans at MetLife Stadium got more than they bargained for Sunday night when the Jonas Brothers turned back the clock, reuniting with Demi Lovato for a surprise "Camp Rock" performance that had the crowd roaring.

The Jonas Brothers kicked off their 20th anniversary tour, "Greetings From Your Hometown," with a hometown show at MetLife Stadium in New Jersey on Sunday, and gave fans an unexpected jolt of nostalgia.

Midway through the set, Kevin, Joe, and Nick Jonas reflected on their breakout Disney Channel film, "Camp Rock," from 2008. As they reminisced, they welcomed a surprise guest to the stage — the movie's lead actress, Demi Lovato.

Lovato, who played Mitchie Torres — the love interest of Joe Jonas's character — also briefly dated Jonas off-screen from March to May 2010.

Videos shared on social media captured the moment Lovato and Jonas performed "Camp Rock" favorites, "This Is Me" and "Wouldn't Change a Thing," sending the stadium into a frenzy.

Lovato is now married to musician Jordan "Jutes" Lutes. Meanwhile, Jonas finalized his divorce from actress Sophie Turner in 2024 after being married for four years.

The Jonas Brothers packed the night with surprises. In addition to Lovato's appearance, they invited Jesse McCartney onstage for a rendition of his 2004 hit "Beautiful Soul," performed alongside the brothers.

Later, the trio was joined by their entire family for an emotional version of "When You Look Me in the Eyes," adding a deeply personal touch to an already heartfelt moment.
