In further proof that exes can be friendly, Demi Lovato made a surprise appearance on Sunday (Aug. 10) at the Jonas Brothers‘ kick-off of their 20th anniversary tour at MetLife Stadium in East Rutherford, N.J., teaming up with former boyfriend Joe Jonas for a trip down memory lane.

The former couple, who played spoiled Connect 3 singer Shane Gray (Jonas) and shy vocalist Mitchie Torres (Lovato) in the Disney Camp Rock movies nearly 20 years ago reconnected for the first time in years at the JONAS20 show with Joe bringing out Lovato to wild screams, according to People magazine.

The couple who back in the day took their on-screen romance into the real world for a short fling in 2010, then belted out the movie hits “This Is Me” and “Wouldn’t Change a Thing” as the audience freaked out about their on-stage reunion. The magazine said that after “This Is Me,” which the pair performed near the end of the 2008 movie, Joe added a few lines from “Gotta Find You,” telling the audience that they hadn’t sung the track together for “almost 10 years,” with Demi saying it “might have been longer.”

In his Instagram Story, Lovato’s husband, Jordan “Jutes” Lutes, shared a snippet of the special moment from backstage, writing, “couldn’t be more proud.. I love u sooo much baby” over footage of the crowd in the stadium losing their minds when Lovato comes out to hug Joe at center stage.

Joe Jonas and Lovato happily leaned into the nostalgia, posted a video after the show of them walking and lip synching along to “Wouldn’t Change a Thing” backstage. On her TikTok, Lovato shared a video of the “Wouldn’t Change” performance along with the message, “thanks for having me @JonasBrothers,” as well as a fun spoof of fellow Disney star Debby Ryan’s “sat down with the President of Disney Channel” speech delivered in sync with Jonas.

The JoBros’ Greetings From Your Hometown tour — whose title is a nod to their just-released album of the same name — moves on to Jiffy Lube Live in Bristow, Va. on Tuesday night (Aug. 12).
