Those dreamy Jonas Brothers will rock with Demi Lovato when "Camp Rock 2: The Final Jam," a full-on musical, lands on the Disney Channel on Sept. 3. The brothers have enjoyed an avalanche of fame but insist that whatever comes along, they stick to a "life plan."

"We are a band first, and whatever we do on the side or divert, we always come back to being a brother band and just make sure who the Jonas Brothers are," says Kevin, the oldest. "For us it's exciting that we can be and do so many different things."
