Clean, Kindly Jonas Bros. Are Suddenly Stars

The Jonas Brothers may rock 'n' roll, but they're also sons of a minister and avowed virgins until marriage. Their lack of bad-boy behavior isn't killing sales, though: An upcoming Jonas tour is already almost sold out. Where did these gentle boy banders come from? An appearance on "Hannah Montana," a run opening for her $36 million tour, and a contract with promoter Live Nation apparently didn't hurt.

Now they have a new record out and a Disney film in the works. But unlike other boy band stars, Kevin, 20, Joe, 18, and Nick, 15, get along well, and even write their own tunes. They still kick it with the family, too: Seven-year old brother Frankie (dubbed "Bonus Jonas" by fans) tags along on tour, and "the catering at the venue will be Grandma," Kevin told Newsweek. "I've already talked to Mom and Dad about it." (More Miley Cyrus stories.)
