Joe Jonas, Demi Lovato Duet Leaks Online

'Camp Rock 2' track 'Wouldn't Change a Thing' is about opposites trying to make their relationship work.

In less than a month, the “Camp Rock 2″ soundtrack will be released, but fans are already getting a taste of what they can expect from it. In a new track leaked online, “Wouldn’t Change a Thing,” Demi Lovato and Joe Jonas sing about two people who, despite being opposites, try to make their relationship work, even if it feels at times like it won’t.

In the chorus, the duo sing, “Like fire and rain/ You can drive me insane/ But I can’t stay mad at you for anything/ We’re like Venus and Mars/ We’re like different stars.” Later on in the song they sing, “We’re perfectly imperfect/ But I wouldn’t change a thing.”

In an interview on Radio Disney earlier this year, Demi said, “['Wouldn't Change a Thing'] is close to my heart. It’s probably one of my favorite parts of the movie.”

“Camp Rock 2″ will premiere on September 3 on the Disney Channel. The soundtrack, which features the new song, will be out on August 10.

While some dates on their upcoming tour have been rescheduled, with the “Camp Rock 2″ tour now kicking off August 7 at First Midwest Bank Amphitheatre in Tinley Park, Illinois, the pair will hit the road this summer for the rest of the Jonas Brothers’ headlining trek. And despite the fact that Joe and Demi broke up in May, Lovato insists she will hold her own with the guys.

“I always hold my own, get it straight!” she joked. “I’m just kidding! It’ll be fun. I’m excited. I’m representing.”

“Wouldn’t Change a Thing” and other “Camp Rock 2″ songs will probably make the set list, but the guys say fans should brace themselves for a full-on JoBros tour. “It’s a Jonas Brothers tour, as usual. We just thought it’d be great to integrate [other] musical outlets as well,” Kevin said. “We thought it was a great way for our opening acts to have a place in the show as well. It’s gonna be fun, ’cause we know everybody. We’ve been doing a movie together for a while.”
