The Jonas Brothers have revealed their secret to keeping energetic and lively all the time – caffeine!

Despite being in their teens, the youthful rocker siblings rely on downing cup after cup of coffee and sports drinks in order to keep up with their busy schedules.

Youngest Brother Nick tells Teen magazine: "I have an energy drink when I wake up and a coffee when I eat breakfast. Then (I have) a coffee at dinner and an energy drink right before I go onstage. Then I'm good."

The trio are indeed keeping busy. The Mandy hitmakers are currently in the middle of a world tour, with dates scheduled until August. Stay tuned to Entertainmentwise for an exclusive with the kids of the future!
