The Jonas Brothers are going to become even more popular with the release of their new Disney movie, "Camp Rock." Our cameras caught up with Kevin, Joe and Nick in New York, where the pop-rock band revealed the inside scoop on their upbringing -- and their encounter with Madonna's 11-year-old daughter, Lourdes.
"She knew about the beginning of the Jonas Brothers and quizzed us," Kevin told "Extra" about Lourdes. "It was really funny." The Jonas Brothers toppled Madonna and Justin Timberlake's hit, "4 Minutes," from the top of the charts with their single, "We Rock."
The brothers also revealed how they all wear purity rings and have vowed to not have sex until they are married. Joe, 18, revealed that the family motto is to "live like you're at the bottom, even if you're at the top. We still do chores, taking out the trash, doing things like that."
